Alumina Ceramics:

The main raw material of alumina ceramic crucible is crystalline natural graphite. Therefore, it retains the various physical and chemical properties of natural graphite. Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heat and rapid cooling. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability. Because of its excellent performance, graphite crucible is widely used in alloy tool steel in metallurgy, foundry, machinery, chemical and other industrial sectors. Smelting and smelting of non-ferrous metals and their alloys. And has a good technical and economic effect. Silicon carbide crucible is a ceramic deep bottom bowl-shaped container. When a solid is to be heated on a large fire, helium must be used. Because it can withstand higher temperatures than glassware. When used, the melted material is usually not filled too much to prevent the heated material from jumping out and allowing air to enter and exit freely for possible oxidation reactions. Because of its small bottom, it is generally required to be placed on the mud triangle to heat directly with fire. It can be placed on the iron tripod with positive or vertical tilting. It can be placed according to the needs of the experiment. After heating, do not immediately place it on a cold metal table to prevent it from rupturing due to rapid cooling. Also do not immediately place on a wooden tabletop to avoid scalding the tabletop or causing a fire. The correct way to do this is to leave it on the iron tripod for natural cooling, or place it on an asbestos net to cool it slowly. Please refer to the pliers for the access.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
