Alumina crucible is a widely used crucible in chemical experiments. Because of its superior performance, it is widely used in chemical experiments. Laboratory applications are also becoming more and more frequent, especially suitable for metal and non-metal sample analysis and melting materials. Next, we will introduce alumina crucible and its uses.
oxidation Aluminum crucible is also called corundum crucible. The main shapes include cylindrical, conical, arc, sagger and other shapes. The purity of alumina crucible is relatively high, containing more than 99% span>AL2O3, 99%Alumina materials are used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valves , so it has good chemical corrosion resistance and temperature resistance, and can be used for a long time in1650℃, can also be used at temperatures up to1800℃, but only for short-term use.

oxidation Aluminum crucibles have good resistance to rapid cooling and heating, and are not easy to explode. Because the alumina crucible is slip-molded, it has a high density. The corundum crucible has good high-temperature insulation and mechanical strength in oxidation and reduction atmospheres, with large thermal conductivity and small thermal expansion rate. In1700℃ and above do not react with air, hydrogen, water vapor, carbon monoxide, etc.
oxidation Aluminum crucibles also include thermal analysis crucibles. Thermal analysis crucibles are mainly used for laboratory analysis. TGAinstrument use. Thermal analysis crucibles have high thermal conductivity and can The heat transfer speed between the crucible and the crucible is fast,to ensure that there is a very small temperature difference between the two,The temperature distribution is uniform. The structural performance is stable, and the high-purity powder is combined with a precisely controlled high-temperature sintering process to form a dense and uniform The microscopic crystal phase structure ensures that there will be no peaks during use, and it is not prone to physical and chemical reactions with the analyzed samples. It has ultra-high temperature stability and a wide operating temperature range,Higher operating temperature can reach1750< /span>High reusability, washable or10% span>Hydrochloric acid washing, drying, can be used repeatedly, Does not affect the experimental results

Alumina crucible is widely used and can be used for various laboratory metal and non-metal sample analysis and melt materials It can also be used for burning color materials, toners, frits, pigments, luminescent materials, etc. in shuttle kilns and push plate kilns, small experimental kilns, experimental electric furnace preparations, etc.; for melting metals, precious metals, and optical glass. It is suitable for the analysis and firing of mineral raw materials such as rare earths and the firing of high-temperature products such as ceramic powders.
Alumina crucible is a deeper development and exploration of crucible technology. Today It is used in more and more practical applications and will bring more convenience to our lives in the future.
