Abstract：
 The invention discloses a method for preparing porous silicon carbide ceramic with high porosity which comprises preparing mix-coated powder from silicon powder, phenol resin and ethanol by a predetermined proportion, then carrying out low-temperature low-pressure modeling to produce ceramic blanks, high temperature carbonizing the ceramic blanks, finally sintering at high temperature to obtain the end product whose factor of porosity is greater than 80%.
