Green silicon carbide powder D50: 1 micron for making semiconductor GAP thermal pads
Brief introduction of green silicon carbide powder D50: 1 micron for making semiconductor GAP thermal pads
Green Silicon Carbide powder D50: 1 micron abrasives is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K).
Green Silicon carbide powder D50: 1 micron also has high strength at elevated temperatures (at 1000°C,Green Silicon carbide grainsis 7.5 times stronger than Al2O3).
Green Silicon carbide powder D50: 1 micron has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C;
Green Silicon carbide powder D50: 1 micron does not melt at normal pressures but instead dissociates at 2815.5°C.
Green Silicon carbide powder D50: 1 micron is an entirely new batch composition made from Silica sand and coke, and is extremely pure.
Green Silicon carbide powder D50: 1 micron can be manufactured in many complex bonded shapes, which are utilized for superrefractory purposes.
Green Silicon carbide powder D50: 1 micron also ideal for a wide variety of abrasive applications.
