Aluminum oxide ceramic linings are made with high alumina under 1500 degree temperature firing in kiln. It has high compression strength, low wear resistance and high hardness. There are all kinds of shape, such as square, rectangle, sleeve,cylinder and some special shape.
It is one of the most stable chemical properties and the highest mechanical strength among refractory oxides; Alumina ceramic does not react with most molten metals, only Mg, Ca, Zr and Ti could have a reducing effect on it above a certain temperature; hot Sulfuric acid can dissolve alumina, and hot HCl and HF also have some corrosive effect on it; the vapor pressure and decomposition pressure of alumina ceramics are the smallest.
Wear resistant alumina ceramic linings is good liner for mineral equipment, can be used in cyclone, pipe, bend, discharge,ball mill, etc. Including 92%, 95% and ZTA series products.
HUAO's wear resistant alumina ceramic tiles can be cut into any shape and are easy to install and maintain. They are suitable for both wet and dry processing applications. Advanced ceramics combine high strength and toughness with extreme hardness to deliver exceptional wear resistance.

Production process of aluminum oxide ceramic Lining
Its production process is relatively complex, mainly including several steps such as raw material preparation, molding, sintering, and post-processing. High purity alumina powder needs to be selected during the production process, and necessary mixing and grinding should be carried out to ensure the uniformity of the raw materials. Then, the mixed raw materials are molded using methods such as pressure molding or injection molding to obtain the desired shape of the blank.
Next, the billet needs to undergo a high-temperature sintering process. The sintering temperature is usually between 1500 degrees Celsius and 1700 degrees Celsius, which not only enhances the density of the material but also improves its mechanical strength. After sintering, the lining bricks will undergo cooling and necessary post-processing such as grinding and polishing to ensure their surface smoothness and flatness.
