Kaolin for Ceramics

In ceramic production, raw materials require a balance between moldability (plasticity) and strength when fired.

Kaolin acts as the "backbone" of the ceramic body. It provides Alumina (Al2O3), which is essential for creating a strong structure during sintering. It also gives the clay body high plasticity, improving Green Strength and preventing warping during firing.

  • High Fired Whiteness (L* > 92%)
  • Increases Green Strength
  • Low shrinkage rate for dimensional control
