摘要：
Highly porous cellular material (HPCM) made from ceramic based on SiC is prepared with addition as a binder of 20% previously synthesized mullite with 1, 3, and 5 wt.% Y2O3 added (above 100% with respect to mullite). The HPCM was prepared by duplicating a matrix of foam polyurethane and sintering at 1350 and 1450°C and has open permeable porosity of about 95%. The ultimate strength in compression of the HPCM obtained did not exceed 0.15 MPa, and for sintered bars that simulate bridges it did not exceed 1.5 MPa. Strength increases with an increase in Y2O3 content and firing temperature.
