Home / High hardness Boron Carbide use for grinding sapphire

The key properties of boron carbide, which are of interest to the designer or engineer, are hardness and the related abrasive wear resistance. a typical example of the optimum use of these properties is in the field of abrasive blasting and water jet cutting, where boron carbide nozzles are used to withstand the harsh wear regime generated by ...
Boron carbide powder for sapphire slicing and polishing applicationsgrade b4c-s-wsp boron carbide is a high performance abrasive material with chemical and physical properties similar to diamonds, such as, chemical resistance and hardness.
Considerable amounts of high-quality boron carbide (b 4 c) are discarded as j240 sapphire-wafer grinding waste (j240-w), which can be mostly recovered and reutilized after purification for environmental protection.
Jan 14, 2020 · boron carbide is mainly made as a controlled rod in a nuclear reactor field, but sometimes it is made into the powder to increase the surface area. at chernobyl nuclear accident in 1986, russia eventually stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.
