Main Application

1

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.

2

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.

3

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.

4

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

5

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.

6

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

7

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.
