Diaspore (AlO(OH)) is a high-alumina mineral recognized for its superior thermal stability, chemical inertness, and high mechanical strength, making it an essential raw material in the refractory and metallurgical industries.
Known for its high alumina content (Al₂O₃: 55-65%) and minimal impurities, diaspore plays a crucial role in advanced industrial applications that demand exceptional resistance to extreme conditions.
At The SK Mining & Industrial Corp. Pvt. Ltd., we are one of India’s leading producers of high-purity diaspore.
Our diaspore is carefully processed to ensure uniformity, consistent performance, and high refractoriness. With a Mohs hardness of 6.5 to 7, it provides outstanding abrasion resistance and wear durability, making it indispensable in refractory linings, foundry molds, and abrasives.
Diaspore offers higher energy efficiency and cost-effectiveness compared to alternatives. Its high melting point of about ~2000°C and thermal shock resistance make it an ideal component in high-performance refractory bricks, kiln linings, and insulating materials for steel, cement, and glass manufacturing.
Diaspore’s low impurity levels and excellent acid resistance also make it a valuable mineral in chemical and metallurgical processes, ensuring longevity and efficiency in harsh environments. Additionally, in the ceramic industry, diaspore enhances mechanical strength, reduces firing shrinkage, and improves thermal expansion control, leading to more durable and energy-efficient products.
As a natural and eco-friendly mineral, diaspore supports sustainable industrial practices by reducing energy consumption, minimizing waste, and promoting resource efficiency. Our responsible mining techniques ensure minimal environmental impact while delivering consistent, high-quality diaspore to meet industry demands.
With our state-of-the-art processing facilities, rigorous quality checks, and tailored solutions, we provide industries with superior-quality diaspore that ensures reliability, sustainability, and cost optimization.
