Abstract: |
The present invention belongs to the field of ceramic material preparing technology, and is especially colloidal state forming process for preparing light high strength ceramic material. The process includes the following steps: preparing suspension with very low solid phase content with special organic monomer, solvent, initiator or chelating agent, and ceramic powder; in-situ solidification through gel polymerization of monomer or high molecular cross-linking to obtain ceramic biscuit; drying, removing binder and no-pressure high temperature sintering to obtain light high strength ceramic material. The present invention can control the porosity and pore size of the ultimate product through altering the solid phase content in the suspension, the sintering condition and the powder size. The present invention has simple technological process, low cost, environment friendship and other advantages, and the produced ceramic material has wide application range. |
