Understanding the Demand for Diamond Anvils in High Pressure Physics

Procurement teams and research groups seeking diamond anvils for high pressure physics experiments face a common set of challenges: identifying a material source with consistent quality, obtaining the correct crystal orientation and NV center density for their specific experimental design, and securing a supplier capable of supporting both fundamental research and, where relevant, industrial-scale deployment. These requirements are especially pronounced in fields such as extreme high-pressure magnetism studies, geoscience and planetary research, and new-state-of-matter exploration, where the diamond anvil itself doubles as a quantum sensing platform rather than a purely mechanical pressure cell.

ViQium Technologies Co., Ltd., headquartered in Minhang District, Shanghai, China, has built its business around exactly this intersection of material science and quantum sensing. Operating under the brand name ViQium, the company focuses on the exploration, scalable fabrication, and industrial application of quantum diamonds and emerging two-dimensional phosphorus-based materials, positioning itself to serve global research institutions and industrial partners with end-to-end capabilities spanning core materials, key devices, and system-level solutions.

ViQium’s NV Diamond Anvil: Engineered for Extreme Conditions

Among ViQium’s Quantum Materials Series, the NV Diamond Anvil is specifically designed for applications that require both mechanical pressure generation and embedded nitrogen-vacancy (NV) center sensing capability. This product is well suited for extreme high-pressure magnetism studies, geoscience and planetary research, and new-state-of-matter exploration—use cases where researchers need to monitor magnetic, temperature, or stress-related changes while samples are subjected to extreme pressure conditions.

Key Product Parameters

The NV Diamond Anvil is offered with the following specifications:

• NV Density: 1–2 ppm
• Anvil Face options: 20 μm, 30 μm, 50 μm, 100 μm, 200 μm, 300 μm
• Anvil Height: 2.35 mm
• Crystal Orientation: <100> and <111>

This range of anvil face sizes allows research teams to match the anvil geometry to their specific pressure cell design and target pressure range, while the available crystal orientations support different experimental geometries for magnetic field sensing during high-pressure experiments.

From Material to Solution: End-to-End Procurement Support

A recurring pain point described by research customers is the lack of clear selection criteria for NV diamond materials. First-time users often find it difficult to determine the optimal crystal orientation and NV center concentration for their specific experimental requirements without purchasing multiple samples for comparison. ViQium addresses this through a comprehensive NV Diamond Selection Guide combined with professional online consultation services, categorizing products according to application requirements so that customers can select the appropriate material without extensive trial-and-error procurement.

This selection support sits within a broader implementation framework. ViQium has established a service process covering requirement alignment, solution design, sample validation, delivery implementation, and application support. Customers typically move through technical communication, solution matching, sample validation, and batch delivery, with overall timelines ranging from several weeks to several months depending on application complexity, and accelerated collaboration available based on specific project requirements.

Why Research Institutions Choose ViQium

ViQium’s founding team draws on academic backgrounds from several leading universities in China, with more than eight years of dedicated research in advanced quantum materials, including NV center quantum diamonds and black phosphorus. This background spans quantum physics, materials science, and optical engineering, combining scientific exploration with precision manufacturing experience.

For research institutes and universities, the core demand lies in obtaining high-quality, reproducible quantum materials and accessible experimental platforms to support fundamental physics validation and scientific discovery. These customers typically prioritize technical performance, product pricing, delivery timelines, and technical support, and their primary challenges include unstable experimental results and insufficient reproducibility, which can limit research efficiency and progress. ViQium’s independently established production process—covering diamond crystal growth, ion irradiation, and high-temperature annealing—is built specifically to address this reproducibility concern, with batch-level control and traceability management applied throughout production and delivery.

For customers working in extreme-environment detection, including geological exploration and aerospace & defense contexts, ViQium notes that decisions in these fields are highly dependent on technical security, confidentiality requirements, long-term system reliability, and proven technological capabilities, with primary challenges centered on overcoming limitations in advanced sensing capabilities caused by dependence on external technology ecosystems and insufficient environmental adaptability.

Customization and Flexible Ordering

Traditional suppliers in this space typically offer limited product options, providing only fixed sizes and specific diamond orientations, which can make it difficult to address specialized experimental requirements. ViQium’s product portfolio is structured to counter this limitation: alongside the NV Diamond Anvil, the company offers (111)-oriented high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds, with customized specifications available for diamond dimensions and NV center concentration.

Standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days. ViQium also supports flexible customization starting from a single piece, which is particularly relevant for research teams that require a specific anvil face size or crystal orientation for a single experimental run rather than a large production batch.

Quality Assurance and Long-Term Reliability

ViQium’s technology platform for fabricating NV centers in diamond relies on both high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) methods, enabling controllable fabrication of quantum diamond materials ranging from single NV centers to ppm-level high-concentration NV center ensembles. The company also holds patented technologies for damage-free fabrication of nitrogen-vacancy centers in diamond, providing technical support for advanced composite processing of superhard materials.

Throughout production and delivery, ViQium implements batch-level control and traceability management to ensure performance stability and consistency across different material batches. Internal access control and information segregation mechanisms are applied to technical information and project data generated during customer applications, supporting the security and independence of technical and application-related data—an important consideration for customers in sensitive research or defense-adjacent programs.

A Trusted Partner for Extreme-Environment Research

Under its slogan, "Sensing the Unseen," ViQium describes its mission as igniting the quantum era through ultimate materials and redefining the boundaries of perception. For procurement teams evaluating diamond anvils for high pressure physics experiments, this translates into a supplier that combines material-level engineering—diamond crystal growth, ion irradiation, and annealing—with application-level understanding of how NV Diamond Anvils are used in extreme high-pressure magnetism studies, geoscience and planetary research, and new-state-of-matter exploration.

With headquarters in Shanghai and a global service network supporting research and industrial customers, ViQium positions itself as a single point of contact for material selection, sample validation, customization, and long-term technical support throughout a customer’s research and development process, from initial material selection to successful application deployment.
