White Ball Clay
White Ball Clay is a high-purity clay material with excellent plasticity, fluidity and binding ability. Produced from carefully selected white clay deposits, it offers stable quality comparable to European ball clay standards. The material is mainly composed of disordered kaolinite with ultra-fine particle size, making it ideal for high-performance refractory and ceramic applications.
Key Quality Features
Extremely low iron oxide and impurity content, ultra-fine particle distribution (–2 μm < 92%), excellent plasticity index (28–32) and refractoriness exceeding 1700 °C. White Ball Clay delivers superior workability and thermal stability for demanding refractory applications.
