Advantages of alumina ceramic crucible for glass melting experiment

1. Alumina ceramic crucible easy to clean and keep clean.Easy to clean after dyeing.

2. Alumina ceramic crucible porcelain hole is very few, water absorption rate is very low.The solution is stored in sealed ceramic crucible to prevent the evaporation, penetration and invasion of foreign bacteria.

3. Alumina ceramic crucible stable chemical properties, durable.This point is better than copper, iron, aluminum and other metal products.

4. Alimina ceramic crucible has a certain acid, alkali, salt and atmospheric carbonate gas erosion ability, not easy to react with these substances, not easy to rust aging.

5. good thermal stability, slow heat transfer.Alumina ceramic crucible has a certain temperature change under the rapid cooling and rapid heat is not easy to crack performance, better than glass, is a bad conductor of heat, heat conduction is slow, used for holding boiling water or hot solution, it is not easy to hot hands.

Applications of alumina ceramic crucible for glass melting experiment

1. Alumina ceramic crucibles are used for high-temperature melting and casting.

2. Alumina ceramic crucibles are used for chemical synthesis and reaction vessels.

3. Alumina ceramic crucible are used for thermal analysis and calorimetry.

4. Alumina ceramic crucible are used for powder calcination and sintering.

5. Alumina ceramic crucible are used for metal alloying and sample preparation.

6. Alumina ceramic crucible are used for catalyst preparation and testing.

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.

FAQ

Q1. Why alumina crucible is used?

A1. Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures. Used as a protector for high-temperature thermal couples. Used as a material for the chemical industry due to its high corrosion resistance.

Q2. What kind of crucible for glass?

A2. Alumina crucibles are inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. Suitable for glass melting, including borosilicate glass.

Q3. What is the difference between alumina and zirconia crucible?

A3. Alumina ceramic could withstand higher temperature, application in industry furnace. 2.As the wear resistance for zirconia is much better, it is frequently used as mortar and pestles, grinding jars.
