Fabrication and Properties of Mullite Fiber-Reinforced Porous Mullite Ceramics

摘要：

　　Porous mullite ceramics reinforced by mullite fiber have been prepared by vacuum filtering with MgO as sintering aid and starch as pore-forming agent.The influence of different sintering temperature and mullite fiber content on porosity and strength of porous mullite ceramics was investigated.The results showed that the compressive strength of the mullite ceramics increased with increasing sintering temperature.With the increase of mullite fiber content,the compressive strength of porous mullite ceramics appeared to increase at first and then decrease.And the peaking strength could reach 211MPa with 36.8% porosity when 7 vol% mullite fiber was added and sintering temperature of 1500 ℃ was adopted.
