Preparation and high temperature performance of silicon carbide foams using aluminum dihydrogen phosphate bonding method at low temperature
Silicon carbide foam ceramics were prepared by using aluminum dihydrogen phosphate as binder and silicon carbide micro powder as aggregate at a low temperature of 800℃. The effects of aluminum dihydrogen phosphate content, solid phase content and elevated temperature treatment on linear shrinkage, bulk density, flexural strength, porosity and microstructure of SIC foam ceramics were …
