Dynamic Ceramic Manufacture and Processing of …

Hot Pressing This forming technique is the simultaneous appliion of external pressure and temperature to enhance densifiion. It is conducted by placing either powder or a compacted preform into a suitable die, typically graphite, and applying uniaxial pressure while the entire system is held at an elevated temperature, e.g. 2000°C for SiC.

Hot-pressed boron carbide (HB4C), as one of the hardest materials known, offers excellent chemical and wear resistance for various demanding appliions. Therefore, our HBC nozzles are used for those most wearing abrasives such as alumina and silicon carbide for efficiency-optimized reasons.
