Boron Carbide, Low Temperature Boron Carbide Synthesis
Boron carbide is the third hardest material known after diamond and cubic boron nitride, with
the advantages of being relatively easy to be synthesized and stable up to very high
temperatures.
Boron carbide has a leading role in materials suitable for high performance applications (defence industry, nuclear technology and air-space industry) due to its attractive combination of properties which include high hardness, low density, high melting point, high Young’s Modulus, great resistance to chemical agents, high neutron absorption crosssection, high corrosion and oxidation resistance and excellent thermoelastic and thermoelectric properties.
Commercial processes for the production of boron carbide powder are based on carbothermal and magnesiothermal reduction of boron oxide. When carbon is used both as a reducing agent and a reactant, the process requires heat treatment at around 1700 °C or higher. In addition to high temperature requirement, undesired gas is produced by carbothermal reduction route.
Boron carbide is also produced by the magnesiothermal reduction route at lower temperature, 1000-1200 °C, but impurities and formed MgO are removed by costly post-treatment. Our studies are aimed to obtain high purity boron carbide by using low temperature synthesis
methods.
