【Abstract】 The research results of aluminum titanate ceramic material which were used for producing 6105 ceramic exhaust pipes, pipelines and turbine cover were described. The sintering conditions and effectfs of the different additives on the properties of aluminum titanate ceramics have been studied. The type,amount and adding process of the additives were determined. The obtained material is of the bending strength 51. 3Mpa,thermal conductivity 0. 86w/mk(800℃),thermal expansion coefficent (RT-1000％)1.22×10-6/℃ ,bulk density 3. 32g/m3 and open porosity 3. 7% respectively.更多还原
