Alumina Binder
What is alumina binder? Also called calcium aluminate, alumina binder is a refractory material used for making refractory castable, refractory cement or refractory concrete. The binder binds the refractory materials together, which is used in building various high temperature facilities such as blast furnace, rotary kiln, etc.
Alumina binder is made from alumina bauxite and lime stone. After being sintered or burned, the manufacturer would grind it into fine powder. Aluminate oxide which can tolerate 2050℃ high temperature takes up 50% of the content of this kind of refractory material. And the main chemical composition of the binder is calcium aluminate. The binder appears to be yellow or brown, sometimes light gray.
Alumina binder can be categorized into unshaped refractory material. It is easy to use, transport, can be cast into any shape, and have excellent high temperature performance. There are a great number of alumina binder supplier in china, among whom, Rongsheng Kiln Refractory Material Co., Ltd is a leading one.

Alumina binder is generally used to build cement kiln, rotary kiln and the linings of other high temperature facilities. It is also an important monolithic material to be used in situations such as roof of a furnace where temperature changes greatly and ordinary refractory bricks would shrink and the structure would collapse.
Usually the alumina binder is sold in powder as for transportation convenience. Powder is much lighter than mixed material and can be stored longer. Before using, mix the material with water and refractory aggregate or powder according to a certain ratio. If the binder isn’t mixed with other aggregates it will form more crack under high temperature. The mixture will be hardened under room temperature(the best temperature is 15℃) in a few hours. During the hardening, it would release a large amount of heat. The binder would reach half of its highest compressive strength in 8 hours.
The product can also be used as binders to make all kinds of refractory bricks, balls, etc.
Advantages and Properties of Alumina Binder
Refractoriness of this kind of material is more than 1580 ℃. The binder has such advantages such as high refractoriness(over 1580 ℃), slag resistance, high compressive strength, thermal shock resistance, abrasion resistance, corrosion resistance, high refractoriness under load, etc.
Also, alumina binder is easy to transport and storage. You can mix it right on the sight of constructing. The mixing technique is very simple and handy.
