Al2O3/Alumina Ceramic Crucible
My factory looking for distributors.
Advantages of Al2O3/Alumina Ceramic Crucible
Alumina ceramic crucible is made of aluminum oxide (alumina). Long term use at 1600 ℃, short-term use at 1800 ℃. Alumina ceramic crucibles have excellent resistance to most acids, ensuring the integrity of the sample during the analysis process. It has strong mechanical properties and can prevent deformation or fracture even under high stress conditions. Thermal conductivity ensures uniform heating of the sample, which helps to obtain consistent and reliable results.
Applications of Al2O3/Alumina Ceramic Crucible
1. Alumina ceramic crucibles are used for melting and casting metals and alloys.
2. Alumina ceramic crucibles are used for calcination and sintering of powders.
3. Thermal analysis techniques, such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA)
4. Crucible fusion for X-ray fluorescence (XRF) analysis.
5. Alumina ceramic crucibles are used for the synthesis and purification of compounds in chemical laboratories.
We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect.
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.
6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.

Our factory
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
