Abstract

The invention discloses a bending and thermal shock resistant ceramic blank, a bending and thermal shock resistant ceramic product and a preparation method thereof, belonging to the technical field of ceramic preparation. The ceramic blank comprises kaolin, sodium lignin sulfonate, zirconium nitride, clay, niobium pentoxide, flux, magnesia-aluminum spinel, mullite, albite, alumina and lithium disilicate. The preparation method comprises the following steps: crushing blank raw material, putting the blank raw material into a ball miller, mixing, adding water and ball milling, freeze drying at -23 DEG C until moisture content is 5-8%, and then putting into a die of a press forming machine, and hot pressing for 35-40 min and then demoulding, cooling to 30-40 DEG C, obtaining a blank body, and putting that blank body into a drying oven to dry the blank body for 2-3 hours later, then putting mixture into a kiln to be burnt for 12-18 hours, and obtaining the finished product. The ceramic product made of the blank of the invention has the advantages of high mechanical strength, strong fracture resistance and thermal shock resistance.

Description

technical field [0001] The invention belongs to the technical field of ceramic preparation, and in particular relates to a bending-resistant and thermal-shock-resistant ceramic blank, a bending-resistant and thermal-shock-resistant ceramic product and a preparation method thereof. Background technique [0002] As a big exporter of ceramic products, after a long period of development, China's ceramic production technology has been continuously improved. Good production technology endows ceramic products with various properties, so that ceramic products are more used in people's lives. in production. All kinds of tableware and tea sets can be seen in ceramic products everywhere. These ceramics are not only beautiful in appearance and diverse in shape, but also have the advantages of easy cleaning and corrosion resistance, and are deeply loved by consumers. [0003] However, the market now requires other properties of ceramic products to manufacture ceramic products with bette...
