We've just introduced a new Direct Sintered Silicon Nitride (Si₃N₄) powder-to-part component manufacturing process that provides a high-performance, cost-effective material solution. The material should be of interest to manufacturers looking for a material with a high strength-to-weight ratio, which compares favorably even with metallic nickel-based “superalloys”. The material also exhibits an unusually low coefficient of thermal expansion, which is a useful property for designers working with high temperature applications.

Slight adjustments can be made to some of the properties to accommodate specific customer requirements. Most of the dense materials in the table are resistant to mechanical erosion and chemical attack. STC has performed ASTM testing qualification for certain compositions, in accordance with ASTM D2442.
