Zirconia Crucible Description
Zirconia (ZrO2) Crucibles are great refractory and insulating materials. They have a clean melt at temperatures above 1900°C and above and are specially manufactured for melting superalloys and precious metals. They also have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis.

Frequently Asked Questions (FAQ)
- What temperature range can Zirconia Ceramic Crucibles withstand?
Zirconia ceramic crucibles can withstand extremely high temperatures, typically up to around 2400℃ (4350°F), depending on the specific grade of zirconia and the crucible's design. Zirconia Crucibles manufactured by isostatic pressing is ideal for use up to 1800℃.
- What materials are Zirconia Ceramic Crucibles compatible with?
Zirconia Ceramic Crucibles are compatible with a wide range of materials, including metals, metal oxides, glass, and many types of molten salts.
- What precautions should be taken when using Zirconia Crucibles?
When using zirconia ceramic crucibles, it's important to handle them carefully to avoid breakage or damage, especially when subjected to rapid temperature changes. Additionally, proper personal protective equipment should be worn when working with hot materials.
- Can Zirconia Ceramic Crucibles be used in microwave applications?
Certain types of zirconia ceramics are microwave-compatible, but it's essential to verify the specific product's suitability for microwave use before attempting to use it in such applications.
- Are there different shapes and sizes of zirconia ceramic crucibles available?
Yes, zirconia ceramic crucibles are available in various shapes and sizes to suit different applications, including cylindrical, conical, and rectangular shapes, as well as different volumes to accommodate varying sample sizes.
