Silicon nitride (Si3N4) is a high-melting-point material with high fracture toughness and excellent thermal shock resistance, It is considered to be one of the few monolithic ceramic materials that can withstand severe thermal shock and thermal gradient generated by hydrogen and oxygen rocket engines.
Silicon Nitride (Si3N4) is 60% lighter than steel but strong enough to survive some of the most demanding applications in a variety of industries. This lightweight, the high-strength ceramic material is used as an alternative to stainless steel, super alloys, tungsten carbides, and first-generation ceramics such as Al2O3 and ZrO2. It offers excellent thermal shock resistance and high fracture toughness, compatibility with nonferrous metal melts, and improved structural reliability compared to other ceramic materials.
When extreme conditions like these push equipment to its limits, Silicon Nitride (Si3N4) industrial ceramics deliver high performance where other materials fail. Typically, Heavy-duty diesel engines. Jet engine igniters. Oil wells thousands of feet underground.
Applications for silicon nitride include:
Foundries
Electronics
Oil & Gas
Automotive
Aerospace
