Description

Technical field [0001] The invention relates to a ball clay that can be used as a raw material for ultra-white polished ceramic tiles, and also relates to a production method of the ball clay. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for decoration, and the quality and whiteness of ceramic tiles used in decoration are also becoming more and more sophisticated. The ceramic manufacturing industry strives to develop ultra-white polished ceramic tiles. However, if the raw materials used in the ceramic manufacturing industry lack the whiteness of more than 80 degrees after high temperature calcination at 1180℃ (the whiteness is China National Standard QB / T1503-1992 "Daily Use The whiteness specified in the Ceramic Whiteness Test Method) and the ball clay with good processing technology and other properties cannot mass produce ultra-white polished tiles. Therefore, due to the raw materials, it is diffi...
