英文摘要	Al3BC3-based porous ceramics are prepared by pressureless sintering using Al, B4C, and graphite powders as the starting materials. The influences of molar ratio of starting materials on the purity, open porosity and pore size of the porous ceramics are investigated. Graphite is the main impurity of the Al3BC3-based porous ceramics and can be eliminated by adjusting the molar ratio of starting material. With the molar ratio of Al:B4C:C = 3.2:0.25:2.30, high pure Al3BC3 porous ceramic is successfully fabricated by pressureless sintering in vacuum at 1800 °C for 2 h. The open porosity of the Al3BC3-based porous ceramics ranges from 36% to 47%. The pores are uniformly distributed.
