Synthesis of Boron carbide
and its typical propertiesTo synthesize B4C powder, the common technique is to combine boron anhydride and excess carbon.
2B2O3+7C→B4+6CO↑
You can either use an electric arc furnace or a muffle oven to perform the reaction. The resistance furnace can synthesize B4C by heating the mixture B2O3-carbon C at a temperature below B4C. (sometimes with Free B 1%-2%) is another better method. B4C is decomposed at 2200 when it is made in an electric furnace. This is because of the high arc temperatures. The quality of B4C produced is affected by the volatilization of some of its components, which can result in a high level of C (usually between 20-30%) in the reaction products. Boric acid, artificial graphite, fixed carbon greater that 95%), and petroleum coke (fixed carb greater than 15%) are all used in the production of B4C. About 2% is the theoretical amount. 50 percent of the total carbon addition amount comes from petroleum coke and artificial graphite. This is about 3%-4% higher than the theoretical value. By reducing or carbonizing the furnace between 1700 and 2300, the three ingredients can be mixed together in a mill. To obtain different particle sizes of B4C, the frit must be separated, washed, pickedled, crushed, ground and pickled. Buffalotours (aka. Buffalotours advanced materials.
