Subject: Substrate Supply Inquiry – 20×20 mm Single-Crystal Diamond for Industrial Gas Detection & Safety Systems
Dear Maeil Industrial Team,
My name is Dhrumil Rangani, Co-Founder of Karia Technologies (USA). I’m reaching out because Maeil Industrial’s expertise in gas detection systems, explosion-proof safety equipment, and industrial hazard monitoring technologies aligns closely with advanced material capabilities we have been developing for extreme environments.
At Karia Technologies, we manufacture optical- and electronic-grade single-crystal CVD diamond wafers, including an industry-unique monolithic format up to 20 × 20 mm. Unlike mosaiced or tiled substrates, our monolithic diamond wafers provide exceptional chemical inertness, ultra-high thermal conductivity, and optical-grade surface quality, making them highly suitable for harsh industrial sensing environments.
Key substrate properties:
Single-crystal CVD diamond (monolithic, no mosaicing)
Industry-unique size: up to 20 × 20 mm
Thickness: ~0.3–4.0 mm (custom thickness available)
Optical-grade, double-side polished surfaces
Thermal conductivity: > 2,000 W/m·K
Extremely low impurity and defect density for harsh environments
Given Maeil Industrial’s role in gas detection, explosion-proof systems, and safety monitoring equipment for hazardous industrial environments, diamond substrates may provide value in applications where sensor durability, chemical resistance, and long-term stability under extreme conditions are critical.
Diamond’s combination of chemical inertness, thermal stability, and mechanical robustness makes it particularly suitable for:
Protective windows for gas sensing and detection systems
Harsh-environment optical sensor interfaces
High-temperature industrial safety monitoring devices
Explosion-proof inspection and diagnostic systems
Long-life calibration or reference components in gas detection equipment
From a commercial perspective, our 20 × 20 mm single-crystal wafers are typically priced at approximately USD 550–650 per wafer, depending on volume — significantly lower than many legacy suppliers of comparable monolithic diamond substrates. This enables practical evaluation for industrial safety R&D and potential integration into next-generation gas detection systems.
We would welcome the opportunity to:
Share detailed material specifications and datasheets
Provide evaluation samples for sensor compatibility testing
Discuss potential integration into Maeil Industrial’s gas detection and safety systems
Explore a possible supply partnership
If this is of interest, I would be glad to arrange a brief technical discussion or provide additional documentation.
Warm regards,
Dhrumil Rangani
