Abstract

The invention provides a high-strength ceramic product and a preparation process thereof. The specific steps of the preparation process are: S1: preparing fiber ceramic balls; S2: mixing materials: by weight fraction, 40-50 parts of ceramic powder, 5 parts of magnetite ‑10 parts, 6‑12 parts of chromite and 3‑7 parts of phenolic resin, put into a ball mill and grind for 1 hour, then add 30‑40 parts of fiber ceramic balls in step 1, and continue ball milling for 9‑10 hours to make ceramics Blank; S3: mold loading: fill the ceramic blank in step S2 in the mold, after extrusion molding, demoulding into a green body; S4: sintering: the made green body is first dried in a drying room, and then in a sintering furnace Sintered to obtain ceramic products. In the preparation process of the high-strength ceramics of the present invention, fiber ceramic balls are obtained by pre-sintering and decomposing, and then synthetic ceramics are obtained through mixing, molding and sintering, and the dispersion is uniform, and the strength and toughness are also improved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-strength ceramic product and a preparation process thereof. Background technique [0002] With the development of science and technology, various new materials have sprung up, and ceramic materials are one of them. Ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds through molding or high-temperature calcination. There are many types of ceramics and different uses. With the development of modern science and technology, many new ceramic varieties have emerged in the past century, and structural ceramics are one of them. In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their high toughness, high flexural strength, high wear resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel. Mainly include: Y-TZP grinding balls,...
