Staying Ahead of Crystal Supply Constraints: How PI-KEM Keeps Your Research Moving

Crystal supply is tightening – but your research doesn’t have to slow down

Across photonics, thin films, semiconductors and advanced device research, demand for high-quality single crystals and substrates has never been higher. At the same time, export controls, logistics challenges and tighter environmental regulations are putting additional pressure on global supply chains.

For many labs and product development teams, this means longer lead times, reduced product choice and more uncertainty when planning experiments or production runs.

At PI-KEM, we’ve taken a different approach. For more than 30 years, we’ve carefully managed our crystal and substrate supply chains through long-standing relationships with specialist growers and high-purity materials manufacturers. The result: a resilient, technically capable supply route that helps keep your projects on track, even when other channels are restricted.

"The single crystal plate that we received has high quality according to our magnetization and magnetic resonance experiments. We are really satisfied with them. Actually, they are much better compared to other sources."

‍Long-term specialist partnerships, not opportunistic sourcing

Rather than chasing spot-buys or short-term stock, PI-KEM has invested in building relationships with expert producers of single crystals, substrates and ultra-high purity compounds. These partners focus on crystal growth, processing and finishing for demanding electronic, photonic and energy applications.

Working in this way means we can:

- Draw on decades of combined experience in crystal growth and processing

- Access a broad range of materials, orientations and dopants for complex projects

- Plan production and stock levels in collaboration with our partners, not reactively

For you, that translates into a more reliable, predictable route to the crystals you need and a team who can explain what’s possible when supply is tight.

‍Technical understanding as part of the supply‍

Availability alone isn’t enough. The crystal or substrate you specify directly affects device performance, repeatability and yield.

Our team works daily with high-purity materials, single crystal substrates and wafers across applications such as epitaxial growth, thin film deposition, sensors, superconducting devices and biomedical components.

When you talk PI-KEM, you are not just placing an order – you’re tapping into technical insight that can help you:

• Select suitable crystal materials, orientations and sizes for your process
• Understand trade-offs when your preferred option is constrained
• Explore alternative materials or formats that still meet your performance requirements

This combination of secure supply routes and technical understanding is what allows us to keep supporting customers even as global supply conditions shift.

Where are we seeing the most pressure?

Customers are reporting increasing difficulty sourcing:

• Specialist single crystal substrates for thin film and nanotech research
• Optical-grade crystals for photonics, optoelectronics and quantum-related devices
• Ultra-high purity compounds used as starting materials for crystal growth
• Reliable and repeatable material quality across batches, with specifications within precise project tolerances

In many of these areas, PI-KEM is still able to support projects with practical lead times and clear technical guidance, thanks to our managed relationships and broad product portfolio.

Planning ahead – and securing supply now

Whether you are in early-stage research or scaling towards production, our aim is straightforward: to keep the right crystal materials flowing into your lab or line – not just in principle, but in practice, today.

Because we’ve actively managed and diversified our crystal supply chains for more than 30 years, PI-KEM is not solely reliant on unpredictable trade routes. Our long-term relationships with carefully selected specialist partners mean that, even as some channels tighten, we are still able to supply many of the key crystals and substrates our customers need right now.

Talk to us about your crystal requirements

If you’re finding crystal supply more difficult – or you’re about to start a project that depends on specialist substrates or high-purity starting materials – we’d strongly recommend a short conversation with our team.

Share your current specifications, challenges and timescales, and we’ll:

• Confirm what we can supply now through our existing routes
• Outline practical options and alternatives if your preferred choice is constrained
• Help you plan a more resilient, longer-term supply route for your work
