Requirements of Round Calcium Stabilized Zirconia Porcelain Crucible

Product and Make-up

This crucible is made from high-purity zirconia (ZrO ₂) stabilized with calcium oxide (CaO). The calcium stabilization provides the material exceptional thermal shock resistance and architectural stamina at heats. The normal zirconia material mores than 94%, with calcium oxide included regulated total up to keep stability during duplicated home heating cycles.

Physical Dimensions

The crucible has a typical cylindrical shape. Common sizes include internal diameters from 20 mm to 100 mm, elevations from 25 mm to 120 mm, and wall surface densities between 2 mm and 5 mm. Custom-made dimensions are readily available upon demand to suit certain laboratory or commercial requirements.

Thermal Efficiency

Optimum running temperature level: up to 2,200 ° C( 4,000 ° F) in air.
Thermal shock resistance: really high– can endure fast cooling and heating without splitting.
Reduced thermal conductivity: helps maintain consistent internal temperature level throughout usage.

Chemical Resistance

The crucible shows solid resistance to molten metals, slags, and lots of aggressive chemicals. It does not react conveniently with the majority of oxides, making it perfect for melting, sintering, and high-temperature evaluation. Avoid call with hydrofluoric acid and strong alkalis at raised temperatures, as these can weaken the zirconia structure.

Mechanical Characteristics

Thickness: approximately 5.6– 5.8 g/cm ³.
Firmness: around 1200 HV (Vickers).
Flexural strength: 200– 300 MPa at area temperature.

Applications

This refractory crucible is extensively utilized in research laboratories for example blend, ash screening, and high-temperature reactions. Industries likewise use it in metallurgy, porcelains, and progressed products processing where contamination needs to be prevented and severe heat is required.

5 FAQs of Cylindrical Calcium Stabilized Zirconia Ceramic Crucible , Zirconia Crucible, Refractory Crucible

Frequently Asked Questions About Cylindrical Calcium-Stabilized Zirconia Ceramic Crucibles

What is a calcium-stabilized zirconia crucible?

This crucible is made from zirconium dioxide (zirconia) with added calcium oxide. The calcium stabilizes the crystal structure so the material stays strong at very high temperatures. It keeps its shape and does not crack easily during heating or cooling cycles.

Why choose zirconia over other refractory materials?

Zirconia has a much higher melting point than most ceramics—over 2,700°C. It resists chemical attack from many molten metals and slags. It also has low thermal conductivity, which helps control heat distribution in your process. These traits make it ideal for demanding lab and industrial uses.

Can this crucible handle repeated heating and cooling?

Yes. Calcium-stabilized zirconia shows excellent thermal shock resistance. You can heat it quickly or cool it down without worrying about cracks or breakage. This durability supports long-term use in high-temperature applications like metal melting or ash testing.

Is the cylindrical shape important?

The cylindrical design offers uniform wall thickness and even heat distribution. It fits well in standard furnaces and allows easy handling with tongs or lifters. This shape also minimizes stress points that could lead to failure during use.

How do I clean and maintain the crucible?
Let the crucible cool completely before cleaning. Remove residues with a soft brush or gentle scraping. Avoid sudden temperature changes and harsh chemicals that might damage the surface. Store it in a dry place to prevent moisture absorption, which can affect performance in future runs.
