Problems solved by technology

However, most of the existing daily-use ceramics have the problem of insufficient wear-resistant and compressive strength. These daily-use ceramic products will inevitably be squeezed, bumped, scratched or worn during normal use. Easy to damage or leave scratches, cracks or gaps on the product, causing flaws, affecting the beauty and even use of ceramic products

Abstract

The invention discloses a wear-resistant and high-hardness ceramic product and a preparation method thereof. The wear-resistant and high-hardness ceramic product comprises a green body and a glaze layer applied on the green body. The green body comprises the following raw materials by weight: 45-55 parts of kaolin, 5-10 parts of zirconia, 12-18 parts of bentonite, 15-25 parts of waste ceramic residue, 10-15 parts of silicon nitride, 17-23 parts of potassium feldspar, and 8-16 parts of albite. The glaze layer consists of the following raw materials by weight: 25-35 parts of kaolin, 12-16 partsof talc powder, 10-15 parts of spodumene, 6-12 parts of lithium china stone, 10-15 parts of quartz, 5-10 parts of silicon carbide and 7-14 parts of calcite. By the above way, the ceramic product provided by the invention has high hardness and wear resistance, high compressive strength and strong thermal stability.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a wear-resistant high-hardness ceramic product and a preparation method thereof. Background technique [0002] Ceramics is an indispensable special product in human life and production. It has a history of thousands of years in the history of human production! In the long history of human development, people have made full use of the physical and chemical properties of ceramic materials to develop a variety of ceramic products such as daily-use ceramics, architectural ceramics, sanitary ceramics, artistic ceramics, and special ceramics. Among them, daily-use ceramics are the oldest and most commonly used traditional ceramics among a wide variety of ceramic products. This type of ceramic products has the widest practicality and appreciation. However, most of the existing daily-use ceramics have the problem of insufficient wear-resistant and compressive strength. These daily-use ...
