Core Index: Al₂O₃ 24±1% | Whiteness 61±2

This product is a high-aluminum and low-iron type nepheline. The content of alumina is close to 24%, which can significantly enhance the density and mechanical strength of the body, and has excellent high-temperature stability. The extremely low loss on ignition means that the firing shrinkage is small and the dimensional accuracy is high. It is particularly suitable for high-end daily-use fine porcelain such as thin-body high-white porcelain, bone ash porcelain, and talc porcelain. The whiteness is close to 61, and the iron and titanium impurities are strictly controlled, which can maximize the retention of the porcelain body's whiteness and transparency. It is the preferred raw material for producing high-value-added white porcelain products.
