Self-propagating high temperature synthesis

Self-propagating high temperature synthesis (SHS) is the use of compound synthesis heat of reaction, the reaction to proceed a process method By physical and chemical research institute of the Soviet union MerzhahovG, BorovlnskayaLp invention, and a variety of high purity was prepared successfully ceramic powder, such as B4C BN Since this method during the preparation of boron carbide with magnesium as fluxing agent, so, also called magnesium hot compared with other methods, has a lower reaction temperature (1273 ~ 1473 k) to save energyTherefore, the purity of the synthesized boron carbide powder is high and the original powder size is fine (0.1-4μm). Generally, it does not need crushing treatment. Therefore, it is the best method to synthesize boron carbide powder at present.
