Choose by Application

Thermal Management and Electrical Insulation

For thermally conductive and electrically insulating systems, aluminum nitride and hexagonal boron nitride are widely considered. Compare thermal conductivity, insulation requirements, particle size, filler loading, thermal expansion, and the intended processing method.

Wear Resistance, Cutting, and Surface Coatings

Titanium nitride, chromium nitride, zirconium nitride, tantalum nitride, and cubic boron nitride are commonly selected for hard and wear-resistant applications. Consider the substrate, deposition process, coating thickness, friction conditions, and operating temperature.

Structural Ceramics and High-Temperature Components

Silicon nitride and aluminum nitride are used in demanding ceramic applications requiring strength, thermal-shock resistance, thermal management, or chemical durability. Powder characteristics, sintering route, oxygen content, density, and final geometry are important selection factors.

Semiconductor and Optoelectronic Materials

GaN, AlGaN, InGaN, InN, and related nitride systems are relevant to power devices, RF electronics, lighting, lasers, and thin-film research. Material selection should account for crystal phase, doping requirements, defect control, substrate compatibility, and fabrication route.
