Ball Clay
A fine-grained natural clay with high plasticity and strong binding properties, supporting workability, green strength, and controlled firing across ceramics, foundries, and coatings.
Product Overview: Natural Ball Clay
Ball Clay is a fine-grained, highly plastic sedimentary natural clay with strong binding properties. It plays an essential role in supporting processing and performance across ceramic, foundry, paper, and coating formulations. Its fine particle structure and superior green strength impart exceptional workability, shaping precision, and crack-resistant drying and firing behavior.
In ceramic whiteware, sanitaryware, and tableware systems, Sakthima Ball Clay contributes to shaping strength and controlled vitrification; in foundry applications, it supports mould cohesion and thermal stability; while in paper and specialty coatings, it enhances surface smoothness, suspension stability, and rheological performance.
