method for producing a body of acicular mullite, calcined body precursor of porous mullite, body of porous acular mullite and carrier of porous acular mullite

摘要

Highly porous acicular mullite bodies are prepared. A green body containing mullite precursors and a porogen is formed using a wet method. The green body is heated to sequentially remove any binder, the porogen and calcine it. The calcined body is mullitized. The process formed a calcined body that has excellent strength and can be handled easily. The mullitized body has very high porosity, small pores and has excellent fracture strength.
