C. It is used for the analysis and firing of rare earth and other mineral raw materials, and the firing of high-temperature products such as ceramic powder.

Al2O3/Alumina Ceramic Crucible


 My factory looking for distributors.


Alumina ceramic crucible is made of alumina as the main raw material and plastic refractory clay as the binder, which is made by mixing with different types of clinker.

Alumina ceramic crucibles are mainly used for smelting special alloy steel, refractory graphite crucibles that melt non-ferrous metals and their alloys! And can be used to fire color TV powder, phosphors, rare earth materials, precious metal materials, high-, medium- and low-temperature ceramic capacitors NTC, PTC The best baking container for piezoelectric ceramics and lithium cobaltate and lithium manganate powder!

Alumina Ceramic


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.

Crucible

 

Component Analysis Alumina Ceramic Crucible Mainly Using

1. Burning solid substances

2. Evaporation, concentration or crystallization of the solution

3. Component analysis alumina ceramic crucibles are suitable for melting samples with anhydrous Na2C03 and other weakly alkaline substances as fluxes, laboratory test crucibles are not suitable for melting samples with Na 202, NaOH and other strongly alkaline substances and acidic substances (such as K2S 207 and so on) as fluxes.
