Reputation depends on quality, quality comes from Hard!
Grouting is the earliest molding method for alumina wear-resistant ceramics. Due to the use of plaster molds, the cost is low and it is easy to form large-sized, complex-shaped parts. The key to grout molding is the preparation of alumina slurries. Usually, water is used as a flux medium, and then a debonding agent and a binder are added, fully ground, and then vented, and then poured into a plaster mold. The slurry is solidified in the mold due to the adsorption of moisture by the gypsum mold capillary. In the hollow grouting, when the mold wall adsorbs the slurry to the required thickness, the excess slurry needs to be poured out. In order to reduce the shrinkage of the green body, a high concentration slurry should be used as much as possible.
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
