Brief Description
Silica bricks are a kind of high quality refractory brick with high refractoriness of 1770~1830℃ and high refractoriness under load of 1500~1650℃, whose physical and chemical property is better than high alumina bricks. Sillimanite transforms into mullite and free silicon dioxide after high temperature firing. Sillimanite refractory bricks generally adopt manufacturing process of high temperature firing and mud mix pouring process.
