Abstract

The invention relates to the technical field of ceramic tableware, specifically to surface nitridation ceramic tableware. The surface nitridation ceramic tableware is composed of the following ingredients (by weight): 10-16 parts of illite, 36-40 parts of Xingzi kaolin, 2-4 parts of red copper fiber, 8-12 parts of black mud, 2-4 parts of boron nitride powder having a hexagonal system, 1-2 parts of potassium titanate whisker, 6-10 parts of expanded vermiculite, 1-2 parts of diatomite, 4-6 parts of ceramic polished waste, 4-6 parts of carnallite and 4-6 parts of an auxiliary agent. The tableware has good caking property of the raw materials. As a nitriding layer of 4-8 mm thick is formed on the surface of the tableware, strength and wear resistance of the tableware are greatly enhanced, and the tableware is resistant to collision. Meanwhile, a compact interlayer is formed on the surface of the tableware to avoid oxidization of the tableware and infiltration of pigments into the tableware so as to prevent from damaging beauty of the tableware. Therefore, the tableware has stable performance and is nontoxic.

Description

Technical field [0001] The invention relates to the technical field of ceramic tableware, in particular to a surface nitriding ceramic tableware and a preparation process thereof. Background technique [0002] Vessels made with clay are called pottery, and vessels made with china clay are called porcelain. Ceramics is the general term for pottery, stoneware and porcelain. Any utensils made from two different types of clay, namely pottery clay and china clay, after batching, molding, drying, and roasting, can be called ceramics. [0003] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics are of unique significance. Different dynasties and generations in Chinese history have different artistic styles and different technical characteristics. The "china"...
