| titleOfInvention | A kind of preparation method of high-strength alumina ceramics |
| abstract | The invention includes a preparation method of high-strength alumina ceramics: adding ethyl cellulose into ethyl alcohol ether solution and stirring evenly, then adding aluminum isopropoxide and stirring evenly to remove the ether to obtain a mixed aluminum dissolved solution; The dissolving solution is put into a mold for evaporation treatment to obtain a solid body, then the solid body is left to stand for treatment, sintered, and washed with ethanol to obtain a porous alumina body; the porous alumina body is placed in aluminum isopropoxide. Ultrasonic dispersion in the solution, then heating treatment, nitrogen purging and then cooling down to obtain coated alumina; second standing treatment of coated alumina, constant temperature sintering to obtain prefabricated alumina ceramics; prefabricated alumina ceramics placed in the reaction kettle, The silicon chloride steam is introduced at a constant temperature, and the temperature is slowly lowered after standing to obtain the prefabricated alumina ceramics saturated with adsorption; the prefabricated alumina ceramics saturated with adsorption are allowed to stand for hydrolysis, then heated up, and sintered into ceramics to obtain high-strength alumina ceramics . |
