Boron Carbide
Boron Carbide is the lightest technical ceramic material (2.5 g/cm³) as well as the hardest (second only to diamond).
Boron Carbide Powder is mainly produced by reacting carbon with B2O3 in an electric arc furnace, through carbo thermal reduction or by gas phase reactions. For commercial use, B4C powders usually need to be milled and purified to remove metallic impurities.
The difference between round and angular abrasives:
The term "bead blasting" has come to be the generic term for media blasting or "sand blasting". This may be confusing to beginners
Physical And Chemical Properties:
| BRANDS | B (%) | C (%) | Fe2O3 (%) | Si (%) | B4C (%) |
| F60---F150 | 77-80 | 17-19 | 0.25-0.45 | 0.2-0.4 | 96-98 |
| F180—F240 | 76-79 | 17-19 | 0.25-0.45 | 0.2-0.4 | 95-97 |
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 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.
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.
