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

Frequently Asked Questions

What affects the fired color of kaolin?

The iron (Fe2O3) and titanium (TiO2) content are the main factors causing coloration. Darson kaolin is processed to minimize these impurities, resulting in a clean white fired color.

Is it suitable for Slip Casting?

Yes, it is excellent. Our kaolin has excellent rheology (flow properties), helping the slip flow into molds evenly and dry consistently, reducing defects.

Can I use it for Glazes?

Yes. We recommend the Premium Grade (UT-ULTRA) for glazes due to its high fineness and very low impurities, ensuring good adhesion and a smooth finish.
