Ceramic material with high strength and high thermal shock resistance as well as preparation method and application of ceramic material

The invention relates to the technical field of ceramic materials, in particular to a ceramic material with high strength and high thermal shock resistance as well as a preparation method and application thereof. The invention discloses a ceramic material with high strength and high thermal shock resistance. The ceramic material is prepared from the following components in percentage by weight: 92 to 96 percent of Al2O3, 1 to 5 percent of SiO2, 0.5 to 1.5 percent of CaO and 0.05 to 0.5 percent of MgO, according to the high-strength and high-thermal-shock-resistance ceramic material, micropores of 5-30 microns are distributed in the cross section, and the porosity is 1%-3%. According to the high-strength and high-thermal-shock-resistance ceramic material disclosed by the invention, the thermal shock resistance of the aluminum oxide ceramic is improved by adding a proper amount of the sintering aid, the pore-forming agent and the doping phase into the aluminum oxide ceramic; meanwhile, specific glass reacts wit
