Low-clay-system high-whiteness ceramic plate and preparation method thereof
The invention provides a low-clay-system high-whiteness ceramic plate and a preparation method thereof. The high-whiteness ceramic plate comprises a basic mineral, an inorganic binder and micro-expanded aluminum oxide serving as a whitening agent, wherein the inorganic binder accounts for 3-8% of the mass of the base mineral, and the whitening agent accounts for 2-4% of the mass of the base mineral. According to the low-clay-system high-whiteness ceramic plate, impurity intervention is reduced, micro-expansion aluminum oxide cannot be fused in the sintering process of a ceramic green body, numerous interfaces can be formed between the micro-expansion aluminum oxide and a glass phase in ceramic, light is greatly reflected and refracted at the interfaces, and a good opacifying effect is achieved; and the whiteness of the ceramic large plate exceeds 80 degrees, and the radioactivity index of the ceramic large plate is within the national standard range.
本发明提供一种低黏土体系高白陶瓷板及其制备方法。所述高白陶瓷板包括基础矿物、无机粘结剂和作为增白剂的微膨胀氧化铝；其中，无机粘结剂占基础矿物的质量百分比为3~8%，增白剂占基础矿物的质量百分比为2~4%。所述低黏土体系高白陶瓷板减少杂质介入，在陶瓷坯体烧成过程中微膨胀氧化铝不会发生熔融，而且会在陶瓷中与玻璃相形成众多的界面，光在界面处发生大量的反射与折射，达到很好的乳浊效果，获得白度超过80度、放射性指数在国标范围内的陶瓷大板。
