Porcelain
Porcelain quartz is a finely ground, high-purity quartz raw material used in porcelain bodies and high-quality ceramic products. A porcelain body is made up of carefully balanced proportions of kaolin, feldspar and quartz; here the quartz provides the body's mechanical strength and dimensional stability. High-purity (typical SiO₂ 99.8%) fine quartz gives porcelain its whiteness and consistent firing behaviour.
How to Choose Porcelain Quartz
The criteria that define porcelain quartz are clear. High SiO₂ purity and low iron content are critical for porcelain's characteristic whiteness and translucency; impurities can cause colour defects. A fine, controlled grain size ensures the quartz is distributed homogeneously throughout the body and reacts evenly during firing. The quartz balances the body's shrinkage during firing, reducing warping and cracking. A stable composition provides repeatability in fine porcelain production.
Recommended Product for Porcelain
Micronised quartz with a fine, controlled grain size is preferred for porcelain bodies. We can determine the right fineness together according to your formulation.
About Porcelain
What role does quartz play in porcelain?
Quartz gives the porcelain body mechanical strength and dimensional stability, while also contributing to whiteness and translucency.
Why is fine quartz needed for porcelain?
A fine grain size ensures the quartz is distributed homogeneously throughout the body and reacts evenly during firing.
Does quartz purity affect the whiteness of porcelain?
Yes, low iron content is critical for porcelain's characteristic whiteness and translucency.
Is porcelain quartz the same as standard ceramic quartz?
Porcelain generally requires more finely ground quartz of higher purity.
