Kaolin for Ceramics & Tiles

Kaolin (also called China clay)

Ceramic and tile production needs raw materials that give workability during forming or pressing, green strength for handling on the line, and dimensional consistency through drying and firing.

UT-WHITE works as a silica-rich clay component in earthenware, glazed wall tile, and floor tile bodies, providing workable plasticity, helping control shrinkage during drying, and supporting body strength after firing. Its fine D50 4.571 µm improves green strength before the kiln and supports even compaction during dry pressing. Fired bodies take on a cream to buff tone, so UT-WHITE is suited to glazed products where the glaze covers the body.

Performance Characteristics

Silica-Rich Matrix

High silica supports fired strength development; UT-WHITE functions as both a clay and silica source in earthenware and glazed tile body formulations.

Green Strength

Fine D50 4.5 µm particle size provides workable plasticity that improves green strength and reduces cracking during drying before firing.

Low Shrinkage

Helps control shrinkage during drying and firing for consistent dimensions in glazed tiles and earthenware products.

Recommended Grades

Selected grades tailored for ceramic applications, from glazed tiles and earthenware to specialty powder formulations.
