Ceramic

1： Talc

The talc is professional ceramic grade raw mineral . It is used for atomized clay, ceramic body and glaze as well as refractory industries . The powder fineness size type is especially suitable for ceramic glaze spray procession . 

The advantages include:  high purity ( SiO2 higher than 60%) , which means high whiteness ( over 95% ) , but low iron and loss on ignition , allowing the production of blends and bodies free of dark dots as well as low shrinkage after firing with good stability at high temperature to improve work-ability and avoid cracks.

2：Magnesium Oxide

Magnesium as a raw material for ceramics production. 

Magnesium carbonate and Magnesium oxide are used in high performance ceramics, frits and glazes. Magnesia products ensure an increase in quality acting as a fluxing agent. The properties of Magnesium added decreases the firing temperature and the thermal cycle of porcelain while increasing the mechanical properties. It also provides opacity and a matt finish. Thanks to a specific chemistry, the addition of our Magnesium carbonate guaranties the whiteness of the ceramics. 

3：Wollastonite

The advantages include low iron content ( below 0.25% ) , low L.O.I ( shrinking rate , below 2.50% ) and the fine size.

4：Alumina

CHALCO brand, high purity low iron ,and excellent liquidity.

5：Washed Kaolin

Whiteness After Calcined: 85%
