Structural Ceramics Products Of Boron Carbide
And Silicon Carbide
|
Because of their high hardness
and strength, excellent wear and corrosion ,low density, low friction
coefficient good self-lubricate and high temperature properties. Both
silicon carbide and boron carbide components have been widely used
in many industries such as: machinery petroleum chemical, ship, auto,
aviation, aerospace , military and nuclear industry. At present ,
Many developed industry countries are using boron carbide and silicon
carbide components to replace components made of tungsten carbide
and alumina. Some of the applications are listed below: Sand blasting
nozzle, Mechanical seal, Wire drawing mould, Neutron absorption block,
Bulletproof vest, Armor plate. Measuring clap. Bearing, casting mould,
Grinding media, Sealed washer, Slide, Sparging, Drawing, Casting,
Proofing, Corrosion, Resistance, measuring, Grinding ball.
Our boron carbide and silicon carbide
of structural ceramics attribute to the new and high technology field.
They are made of high purity fine boron carbide and silicon carbide
powders specially designed equipment. We can produce a variety of
products based on the requirements of customers. |
