ZC0937 Zirconium Dioxide Crucible (ZrO2 Crucible)

Zirconium Dioxide Crucible Description

Crucibles manufactured from zirconium dioxide (ZrO2) are designed for high-temperature applications. They demonstrate fire resistance and effective insulation. They exhibit a clean melt behaviour at temperatures above 1 900°C and are produced specifically for melting superalloys and precious metals. They also offer chemical inertness, withstand thermal cycling up to 2 200°C and resist corrosion from acids and alkalis.

Specifications of Zirconium Dioxide Crucibles

Zirconium dioxide crucibles are available in various sizes and shapes in accordance with customer requirements.

Applications of Zirconium Dioxide Crucibles

Zirconium dioxide (ZrO2) is used in environments requiring high-temperature resistance, chemical inertness and the ability to withstand thermal cycling up to 2 200°C. High-purity zirconium dioxide crucibles are employed in:

- Chemical calcination
- Metal casting
- Melting of metals, particularly within the superalloy and precious metal industries
- Thermal analysis crucibles

Packaging of Zirconium Dioxide Crucibles

Zirconium dioxide crucibles from SAM are handled with care to minimise damage during storage and transit, thereby preserving product quality in its original condition.

Frequently Asked Questions (FAQ)

1. What temperature range can zirconium dioxide ceramic crucibles withstand?

Zirconium dioxide ceramic crucibles can endure temperatures generally up to approximately 2 400°C, depending on the specific zirconium dioxide quality and design of the crucible. Crucibles produced via isostatic pressing are rated for use up to 1 800°C.

2. With which materials are zirconium dioxide ceramic crucibles compatible?

Zirconium dioxide ceramic crucibles are compatible with a range of materials, including metals, metal oxides, glass and various types of salt mixtures.

3. What precautions should be observed when using zirconium dioxide crucibles?

When using zirconium dioxide ceramic crucibles, it is essential to handle them carefully to prevent breakage or damage, particularly during rapid temperature changes. Personnel should wear the appropriate personal protective equipment when managing heated materials.

4. Can zirconium dioxide ceramic crucibles be used in microwave applications?

Some types of zirconium dioxide ceramics are suitable for microwave applications. It is necessary to verify that the specific product meets the requirements for such use.

5. Are there different shapes and sizes of zirconium dioxide ceramic crucibles?

Zirconium dioxide ceramic crucibles are available in various shapes, including cylindrical, conical and rectangular, and are offered in different volumes to accommodate varying sample sizes.
