Boron carbide production sandblasting machine nozzle of high pressure water cutting machine nozzle sealing ring as ceramic advanced features such as: boron carbide nozzle has the characteristics of abrasion resistant high hardness will gradually replace known hard alloy (tungsten steel) and silicon carbide silicon nitride material such as alumina zirconia sand jet In addition, the application of boron carbide in the field of composite ceramic: boron carbide is a compound of covalent bond is very strong, and boron carbide plastic is very poor, the grain boundary migration resistance is very big, difficult to obtain the density of sintered body, except for some special occasions, such as microcrystalline boron carbide gas dynamic pressure bearing materialUsed as a neutron absorption material of boron carbide in nuclear reactor block, usually use the method of adding sintering additives to improve the sintering behavior of boron carbide, boron carbide products cheaper practical more it is worth noting that the B4C SiC composite ceramic in lower boron carbide ceramic sintering conditions at the same time, can maintain excellent physical and mechanical properties of boron carbide ceramics B4C SiC ceramics was considered a wide application prospect of high temperature corrosion Wear-resistant material, has been in the industry of jet pump seal and hot extrusion die in the fields of application.
