Buy Natural Bulk Kaolin Clay White Clay for Pottery Calcined Kaolin

Product Description

Product Description

Kaolin is a kind of non-metallic mineral. It is a kind of clay and clayrock mainly composed of kaolinite clay minerals. Because of its white and fine, also known as dolomite.Its pure kaolin is white, delicate, soft soil, with good plasticity and fire resistance and other physical and chemical properties.

The kaolin produced by our company mainly includes calcined kaolin, water-washed kaolin and metakaolin(High activity).

Characteristics for kaolin:
1. High refractoriness.
2. Physicochemical stability.
3. Volume density high .
4. Low porosity.
5. Low water absorption.
6. Fully calcined
7. Low impurity content.
8. Pure white.

Application

Ceramics Industry
As the core raw material of ceramics, it improves green strength, whiteness and sintering performance, used in domestic ceramics, building ceramics, sanitary ware, electrical ceramics, art ceramics and special ceramics.
Paper Industry
Used as filler and coating pigment to improve whiteness, smoothness, opacity and printability, reducing production cost. Widely applied in coated paper, offset paper, newsprint, specialty paper, etc.
Coatings Industry
Improves hiding power, weather resistance, suspension and thixotropy of coatings, enhancing application performance. Used in water-based coatings, latex paints, powder coatings, anti-corrosion coatings, architectural coatings, etc.
Plastics & Rubber Industry
In plastics, it enhances rigidity, heat resistance and dimensional stability; in rubber, acts as reinforcing filler to improve wear resistance, anti-aging property and tensile strength. Commonly used in PVC, PE, PP, wires and cables, rubber products.
Refractories & Building Materials
Used in refractory bricks, insulation materials and ceramic fibers; metakaolin can be applied in high-performance concrete, grouting materials and floor mortars to improve strength and durability.
Cosmetics & Daily Chemicals
As a powder raw material with fine texture and strong adsorbability, used in foundations, loose powders, facial masks, soaps, toothpastes, etc., improving skin feel and stability.
Environmental Protection & New Materials
Used as adsorbent for wastewater treatment and soil conditioner; also applied in high-end fields such as petroleum catalysts, ceramic separators, filler carriers and 3D printing ceramic materials.
