Alumina Ceramic Crucible For Glass Melting Experiment
- Yunxing
- China Jinzhou
- 5-30 Days
- 3,000-5,000/month(Looking for distributors)
Advantages of alumina ceramic crucible:
(1) Easy to clean and keep clean. The ceramic crucible has a bright and delicate glazed surface.
(2) There are few porcelain holes and low water absorption. The solution is stored in a sealed ceramic crucible to prevent the evaporation, penetration and intrusion of foreign bacteria.
(3) Stable chemical properties and durability. This is better than copper, iron, aluminum and other metal products.
Alumina Ceramic Crucible For Glass Melting Experiment
My factory looking for distributors.
Advantages of alumina ceramic crucible:
(1) Easy to clean and keep clean.The glaze of ceramic crucible is bright and delicate, easy to clean after dyeing.
(2) 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) stable chemical properties, durable.This point is better than copper, iron, aluminum and other metal products, 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.
(4) 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.
