It can also be used to produce the nozzles of gun and artillery in munitions industry.2For 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.3For 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.4For Other Engineering Ceramic Materials B4C can be prepared into nozzles for sand spraying machine and high pressure water cutter, ring seal, mould for ceramics etc5For 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.6Application 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 good7Application 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.
