1 Material: 100% virgin Zirconia powder
2. Color: white
3 Max use temperature: 2300
4 Corrosion resistance
Zirconia (ZrO2) can withstand the high temperature up to 2300°C and has very good resistance to chemical erosions and thermal shock. Zirconia crucible is ideal for the melting of precious metals and super-alloys. Zirconia crucibles are available in many sizes and shapes. Call for any custom production request.

Purpose |
Main purpose of crucible is as a container for analysis and firing of material and product applied in various industries. For example: analysis of coal, melting of the metal, analysis and firing of chemical raw materials, analysis and melting of glass, analysis and firing of rare earth materials and mineral, firing of high temperature items such as ceramic products and melting of single-crystal raw materials. |
|
Use |
Under normal circumstances, firstly put the items which need to be analyzed and fired into the crucible. Then heat. The speed of heating and drop in temperature are according to the characteristics of equipment and products, fast or slow. Because of the thermal expansion of raw material which the crucibles are made of, too quick heating or cooling will easily lead to cracking of the crucibles. The best way is slowing down, which can prolong the life of them. |
Specification:
We can make various crucibles and saggers made of high zirconia (yttria-stabilized), with different shapes. And we can also custom based on the requirement.
Shapes: Rectangular, Arc, High form, Cylindrical, Circular, Conical, special-shaped
Specification: 5ml 10ml 15ml 20ml 25ml 30ml 50ml 100ml 150ml 200ml-2500ml

Usage:
Under normal circumstances most of the material will be analyzed and used to bake saggar made from different materials within the system first and then placed into the crucible or analysis or fired for heating equipment.
According to the speed and heating equipment and temperature characteristics of the product with drawal, some are faster and some are slower. Because of the crucible and saggar made from different materials with thermal expansion materials.
Crucible easily lead to excessive heating or cooling cracking so it is best to slow down and saggar made from different materials. This will extend the life of crucible and saggar made from different materials.
