Growmore Minerals is a reliable exporter of high-quality China Clay (Kaolin), supplying to global markets with consistent standards and performance. China clay, with the chemical formula Al₂Si₂O₅(OH)₄, is a refined hydrated aluminum silicate known for its high brightness, fine particle size, and excellent purity.
Our China clay is carefully processed using advanced techniques to meet international quality requirements. It is widely used in ceramics, porcelain, paper coating, paints, rubber, and other industrial applications. We ensure controlled moisture content, uniform particle distribution, and low impurity levels in every shipment.
Our products are available in customized grades and packaging options based on buyer specifications. We follow strict quality checks and provide test reports to ensure compliance with global standards. With strong logistics support, we guarantee timely delivery and safe packaging for export consignments.
Growmore Minerals is committed to offering competitive pricing, reliable supply, and long-term business partnerships. We aim to be a trusted sourcing partner for premium China clay across international markets.
Raw kaolin clay (also called China clay) is a naturally occurring soft white mineral primarily composed of hydrated aluminum silicate. Its chemical formula is Al₂Si₂O₅(OH)₄. It is formed by the weathering of feldspar-rich rocks over millions of years.
Raw kaolin is widely used in industries such as ceramics (for tiles, sanitaryware, and porcelain), paper (as a coating and filler material), rubber and plastics (to improve strength and durability), paints and coatings (for brightness and opacity), and pharmaceuticals and cosmetics due to its purity and gentle properties.
Levigated China Clay is a purified and processed form of raw kaolin clay obtained through a wet beneficiation process known as levigation. In this process, raw clay is mixed with water, stirred, and allowed to separate so that finer, lighter particles are collected while impurities like sand, mica, and other coarse materials are removed.
Hydrous kaolin is typically produced by refining raw kaolin through washing and classification processes to remove impurities, resulting in a fine, high-purity product with good whiteness, softness, and controlled particle size.
Calcined Kaolin is a high-performance form of kaolin clay produced by heating (calcination) hydrous kaolin at temperatures typically between 700°C to 1000°C. This heat treatment removes chemically bound water (dehydroxylation) and transforms the clay into a harder, more structured material with enhanced properties.
Refractory clay (also known as fire clay) is a type of heat-resistant clay capable of withstanding very high temperatures without melting, deforming, or losing its strength. It is primarily composed of alumina (Al₂O₃) and silica (SiO₂), along with small amounts of other minerals.
