Product Description
White Ball Clay is a high-purity clay material with excellent plasticity, fluidity, and binding ability. With stable quality comparable to European "Ball Clay" standards, our white ball clay is composed primarily of disordered kaolinite with very fine particle size distribution.
Manually selected high-grade white clay ensures consistent quality and superior performance in demanding applications. The material combines exceptional workability with high refractoriness, making it ideal for refractory applications.
Key Quality Features: Extremely low iron oxide and impurity content, very fine particle distribution (–2 μm < 92%), excellent plasticity index (28–32), and refractoriness exceeding 1700 °C. Perfect for premium refractory applications requiring superior performance.
