Problems solved by technology

However, due to the lack of high-grade purple sand raw materials at present, especially since the mining of Yixing purple sand mineral resources has been restricted by the government since 2005, almost all purple sand products on the market are made of inferior purple sand raw materials or purple sand tailings raw materials plus chemical raw materials ( Fe 2 o 3 , MnO 2 、Co 2 o 3 etc.), which seriously endanger people's health and is not conducive to the application and development of purple sand products

Abstract

The invention discloses a boccaro clay, which is composed of boccaro shale and red mud in a mass ratio of 1-3:1-3. In addition, the invention also discloses a preparation method of the boccaro clay. Without adding other industrial raw material and artificial pigment, boccaro clay with good performance and excellent quality can be obtained, and the prepared boccaro product is natural and environment-friendly, and has excellent performance. At the same time, the preparation process is simple, has strong operability, is convenient for popularization and application and realization of industrialization, and is conducive to promoting boccaro product application and technology development.

Description

technical field [0001] The invention relates to the technical field of ceramic raw materials, in particular to a purple sand mud and a preparation method thereof. Background technique [0002] Zisha pottery is a kind of stoneware, which is a ceramic product between pottery and porcelain. It has the characteristics of compact structure, high strength, thermal shock resistance and good air permeability. A traditional culture that people love. The purple sand ore used for firing purple sand pottery is iron-bearing clayey siltstone, which is composed of hydromica and kaolin, quartz, mica chips and iron and other mineral components. The main chemical components are silicon oxide, aluminum oxide, iron oxide, oxide Calcium, magnesium oxide, manganese oxide, potassium oxide and sodium oxide, etc.; there are many colors, mainly divided into red purple sand, white purple sand, yellow purple sand, purple sand, green purple sand, and black purple sand. However, due to the lack of high...
