Problems solved by technology

The main problem of this preparation method is that the ceramics need to be processed, such as drilling, grooving, etc., due to the brittleness of the ceramics, the yield of this processing method is very low
In addition, since the magnetic substance and the ceramic body have not achieved a permanent and firm connection, it is prone to loosening, shifting and falling off, which restricts its use and affects the appearance of ceramic products.

Abstract

The invention discloses a method for preparing magnetizable ceramic. The method is characterized in that: a magnetizable substance is added into nonmagnetic ceramic powder, and a magnetizable ceramic product is prepared by adopting a ceramic preparation process; and the ceramic preparation process comprises proportioning, blending, shaping and sintering. The magnetizable substance is directly added into the ceramic raw materials, and the magnetizable substance is sintered in a ceramic body by a ceramic high-temperature sintering process at the same time of keeping the original magnetizable property, so that the bonding problem of the magnetizable substance and the ceramic product is solved, the process is simple, the preparation is convenient, and the method has good popularization value.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a preparation method of magnetizable ceramics. Background technique [0002] Ceramics are commonly used materials in people's daily life, especially traditional ceramics, namely construction, bathroom, daily use, arts and crafts ceramics, such as wall and floor tiles, bathroom, tableware and art ceramics, etc. It plays an important role in protecting one's health and is an essential daily necessities for people's lives. At present, the main functions of these ceramic materials are limited to the use characteristics determined by their own materials and processing characteristics. For example, wall and floor tiles are mainly used for decoration and beautification. Sanitary ceramics meet people’s needs for washing and cleaning. Cooking, carrying items and other daily needs. Arts and crafts ceramics meet people's needs for space decoration and collection. The extension ...
