【摘要】:綜述了采用碳熱還原天然礦物、工業(yè)固體廢棄物和前驅(qū)體制備碳化物(Si C、Ti C、B4C、Zr C、Mo2C和Al8B4C7)及碳化硅基復(fù)合粉體(Si C-Al2O3、Si C-Zr O2、Si C-Zr B2、Si C-Si Al ON、Si C-Al6Si2O13、Si C-Ti C、Si C-Zr C)的最新研究進(jìn)展,分析了碳熱還原法制備陶瓷粉體的優(yōu)缺點(diǎn)及合成反應(yīng)機(jī)制,并展望了由天然礦物、固體廢棄物和前驅(qū)體制備碳化物及碳化硅基復(fù)合粉體的發(fā)展前景。
[Abstract]:The latest research progress in the preparation of carbides, such as natural minerals, industrial solid wastes and precursors, by carbothermal reduction of natural minerals, industrial solid wastes and precursors, including the preparation of carbides such as carbides, TiCX, TiCX, Zr, CnMo2C and Al8B4C7, and sic based composite powders, SiC-Al2O3SiO2SiO2SiO2SiO2-Si C-Si Al ONSi C-Al6Si2O13Si2O13Si C-Ti C-Zr C-Zr, is reviewed in this paper. The advantages and disadvantages of the preparation of ceramic powders by carbothermal reduction and the synthetic reaction mechanism were analyzed. The development prospect of the preparation of carbide and sic based composite powders from natural minerals solid wastes and precursors was also prospected.
