Boron Carbide
 

Raw material and process of production:

Boron carbide is a well-known abrasive material and it is third hardest material after diamond and cubic boron nitride. Boron carbide powder finds extensive application as a lapping agent in place of diamond. In the finishing of semi-precious gems such as ruby, synthetic corundum etc., boron carbide powder achieves about 60% of the speed steel and carbide tip tools and wire drawing dies. Fully dense boron carbide is successfully tested as a light weight armor material. Sintered boron carbide shapes are widely used as sand blasting nozzle, hard ceramic bearings and as grinding mortars. It is used in nuclear reactors as shielding and control rod material, as solid rocket propellant in aerospace industry due to its capability to generate tremendous amount of heat (12400 Kcal/Kg) in combination with oxygen and also useful for the preparation of various hard metal borides.

 
Physical And Chemical Properties

 
 
Main Application
 
 
For Other Engineering Ceramic Materials


B4C can be prepared into nozzles for sand spraying machine and high pressure water cutter, ring seal, mould for ceramics etc



For Refractories Industry

B4C can be used as anti-oxidation agent for low carbon magnesia carbon brocks and castables. It can be applied in key positions which suffer from serious erosion and high temperature, such as ladle, taphole(nozzle),sliding plate and stopper.
 

 
Application of B4C on Electrical Property
 
 
B4C-graphite thermocouple is composed of graphite pipe, B4C bar and BN Lining.In inert gases and vacuum, its service temperature is 2200℃,the linear relation of electric potential difference and temperature is good
 
 
 
Application of B4C as Chemical Material

 
After being activated nu halogens, B4C powder can be used as boronation agent of steel and other alloys for boronizing on the steel surface, forming a thin iron boride layer, increasing the strength and wear resistance of the materials.
 
 
For Nuclear Industry

 
B4C can be prepared into controlling bars, adjusting bars, accident bars, safety bars, screen bars, radiation resistant B4C tilts, plate, or neutron absorber(prepared with high B10 content powders),and radiation resistant layer for atomic reactor together with cement which is the most important functional component only next to reactor fuel.
 
 
 
Application of B4C in national defense industry

 
B4C can be used to produce bulletproof materials, such as bulletproof plate in bulletproof vests, ceramic bulletproof tile in military airplane pilot cabin and bulletproof plate in modern armored personnel vehicle and tank. It can also be used to produce the nozzles of gun and artillery in munitions industry.
  
 
 
For Normal Industry Fields

 
B4C is used to prepare: high grade wear-resistant welding rods to strength the wear resistance of welding face; grinding and polishing materials, water cutting abrasives and polishing materials for diamond abrasives tools; polishing and grinding of jewels.
