Abstract

The invention discloses a high-silica porcelain rustic tile and a production method thereof. A green body is prepared from, by weight, 10% of Dalong stone powder, 20% of Yanling potassium sand, 17% ofGuanqian mud, 28% of Longshan sand, 5% of grey feldspar and 20% of Xiongda stone powder, the added ingredients account for, by weight, 1.5-2.5% of the raw materials, the one-step firing temperature is 1202 DEG C, and the firing period is 60-65 minutes. Through optimization of a green body formula and optimization of a corresponding glaze formula, the high-quality rustic tile with the product appearance quality, the product interior quality and the product using performance being not lower than those of the tile produced by using an existing high-aluminum green body formula is obtained by combining a firing technology, and the contradiction that due to special requirements, the raw materials are difficult to obtain is solved.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to ceramic tiles produced by using high-silicon raw materials. Background technique [0002] The mineral raw materials used in the ceramic industry (such as: kaolin, black mud, ball clay, bauxite, feldspar, etc.) are mainly composed of silica, followed by alumina. Considering the important influence of alumina content on the performance of tiles, the industry often judges whether a raw material is a high-quality raw material by the level of alumina content in the raw material. Since the reform and opening up, with the rapid development of the domestic economy and the rapid expansion of the building ceramics industry, high-quality mineral raw materials have become increasingly scarce, which can be reflected in the rising prices of high-quality raw materials. For example, the price of kaolin rose from 561 yuan / ton in 2009 to 708 yuan / ton at its peak; the price of bauxite rose f...
