Abstract

The invention discloses environment-friendly rice husk ash porcelain blank and a preparation method. The environment-friendly rice husk ash porcelain blank is made of, by weight, 30-45 parts of kaolin, 10-15 parts of feldspar, 25-35 parts of quartz and 25-50 parts of rice husk ash. The rice husk ash is used as a production material in a high proportion via repeated compounding tests, and accordingly the problem of shortage of porcelain clay is solved, wastes of crops can be fully used, production cost is reduced, environment is protected, and resources are saved. Further, the problems of blank molding and combination of blank and glaze can be solved, the environment-friendly rice husk ash porcelain can be greenly white, bright and glossy, and characteristics of Chingtechen celadon are truly embodied. Ecological balance is maintained and environment protection is achieved by using wastes of crops.

Description

technical field [0001] The invention relates to a ceramic blank and a preparation method, in particular to an environment-friendly chaff ash ceramic blank and a preparation method that can be used in the fields of high-grade daily-use ceramics and architectural ceramics. Background technique [0002] Ceramic production has a history of thousands of years in the long history of mankind, and daily-use ceramics are one of the oldest and most traditional ceramics among a wide variety of ceramic products. With the continuous improvement of people's living standards, they have a new understanding of the practical nature and environmental protection concept of ceramic products. Due to the increasing demand for ceramic products, the production of ceramics (especially building ceramics) has expanded rapidly, resulting in a shortage of ceramic raw materials. The reason why Jingdezhen has become a world-famous porcelain capital is that Jingdezhen and its surrounding areas have stored ...
