Super white kaolin clay for ceramics(GB-K80)

GB-K80 kaolin is produced through water washing, grind and classification. The well controlled processes ensure the product have no coarse particles, so the end user can achieve a high Hegman grind. The product have high brightness, it is applied in high end ceramice. 1. The kaolin mineral is primarily lily-white and pure white, high purity. 2. Higher aluminum oxide content, lower iron oxide and titanium oxide, in comparison to competitive clays. 3. High natural brightness, the calcined brightness is 94-95% at 1,300 centigrade degree. 4. GB-K80 is one material special for top grad ceramice.
