A. Has high thermal conductivity. The rapid heat transfer between the sample and the crucible ensures that there is a very small temperature difference between the two and the temperature distribution is uniform.
B. Ultra-high temperature stability, wide operating temperature range, higher operating temperature up to 1750 ℃, high repeatability, washing with water or 10% hydrochloric acid, drying, can be used repeatedly, without affecting the experimental results.

My factory looking for distributors.
Alumina crucibles also contain thermal analysis crucibles. Thermal analysis crucibles are mainly used for laboratory analysis. TGA instruments are used. Thermal analysis crucibles have high thermal conductivity and fast heat transfer between the sample and the crucible to ensure that there is a very small amount between the two Temperature difference, uniform temperature distribution. The structure and performance are stable. The high-purity powder cooperates with the precisely controlled high-temperature sintering process to form a dense and uniform micro-crystalline phase structure to ensure that there is no peak during use, and it is difficult to physically or chemically react with the analysis sample. Ultra-high temperature stability, wide operating temperature range, higher operating temperature up to 1750 ℃, high repeatability, washing with water or 10% hydrochloric acid, drying, can be used repeatedly, without affecting the experimental results.
Alumina crucible has a wide range of uses. It can be used in various laboratory metal and non-metal sample analysis and melting materials. It can also be used in shuttle kilns and push plate kilns to burn color materials, colorants, frit, pigments, luminescent materials, etc. . Small experimental kiln, experimental electric furnace adjustment formula and other purposes. Melting metals, precious metals, optical glass, analysis and firing of mineral raw materials such as rare earths, and firing of high-temperature products such as ceramic powder.
