High Thermal Conductivity Silica Bricks are specially developed refractory materials made from high-purity quartzite and select mineral additives. These bricks are manufactured using an optimized firing process to ensure improved thermal conductivity, excellent volume stability, and high performance at elevated temperatures. They are ideal for use in industrial furnaces where rapid heat transfer and energy efficiency are essential.
