Andalusite products are sourced from high-quality deposits and undergo stringent processing to ensure purity and consistency. They are available in various forms, including lumps, powders, and bricks, tailored to meet specific industrial requirements. The mineral's prismatic and anhydrous crystal structure contributes to its high refractoriness and excellent thermal shock resistance. it's ability to transform into mullite at relatively low temperatures (between 1,200°C and 1,550°C) further enhances its refractory properties
