5 FAQs of High Purity Refractory Castable Raw Material White Fused Alumina / High Alumina Castable

White fused alumina is a key raw material for high purity refractory castables. People often have questions about it. Here are five common ones.

What exactly is white fused alumina? White fused alumina is a man-made material. It’s made by melting and then cooling pure aluminum oxide. This process creates a very hard substance. It’s mostly white or light in color. It contains over 99% Al2O3. This high purity is crucial.

Why use white fused alumina in castables? This material brings important qualities. It offers excellent hardness and strength. It resists wear very well. It handles high temperatures effectively. These properties make the final castable last longer. It performs better under tough conditions.

How does its purity help? High purity means very few impurities. Impurities can weaken the castable. They might lower its melting point. Fewer impurities make the castable stronger. They help it resist chemical attacks better. The castable stays stable at high heat longer.

Why does particle size matter? The size of the alumina grains is controlled carefully. Different sizes are used together. This packing affects the castable’s density. Good packing fills spaces efficiently. It makes the castable stronger. It improves how well it resists wear. The right size mix is vital for performance.

How is it different from brown fused alumina? White fused alumina is purer than brown fused alumina. Brown fused alumina has more impurities. It’s usually cheaper. White fused alumina offers better performance. It provides higher strength and better corrosion resistance. Choosing white fused alumina means better quality.
