The invention relates to a preparation method of ceramic materials; the raw materials used in the method comprises alumina powder, titanium oxide powder, synthetic material of aluminium titanate and stabilizing agents, wherein, the stabilizing agents comprise magnesium oxide, silica dioxide, ferric oxide, chromium dioxide and zirconium oxide. The conditions of the preparation process are as follows: firstly, the raw material and water carry out ball milling and pulping by a wet method; secondly, the slurry is granulated and dried into powder with the water content to be less than 2 percent; thirdly, isostatic pressing molding is carried out; fourthly, the powder is sintered into a lift tube of aluminium titanate ceramics under the conditions that the sintering temperature is 1,480 to 1,550 DEG C, the sintering time is 20 to 30 hours and the sintering atmosphere is oxidizing atmosphere; wherein, alumina powder, titanium oxide powder, stabilizing agents and water carry out ball milling and pulping by the wet method and granulation to prepare particle size, then the synthetic material of aluminium titanate is prepared by sintering. The product prepared by the method is characterized by low price, non-infiltration of alumina melt, no reaction, high intensity, strong thermal shock resistant capability, no slag during the using process, long service life, etc.
