Description
High strength white fused alumina castable is a type of refractory material used in high-temperature applications such as furnaces, kilns, and reactors. It is made from high-purity white fused alumina, a synthetic material produced by fusing aluminum oxide powder at high temperatures.
White fused alumina castable is designed to have high strength and excellent thermal shock resistance, making it suitable for use in applications where it will be subjected to high temperatures and rapid temperature changes. It is also highly resistant to corrosion and erosion, making it ideal for use in harsh environments.
The castable is typically made by mixing white fused alumina with a binder and other additives, and then pouring or tamping it into place to form the desired shape. The mixture is then allowed to dry and cure at room temperature or with the help of a controlled heating process.
