High Purity Alumina Kiln Furniture for Muffle Furnace
Product Details:
ZYLAB high purity alumina kiln furniture is made from alumina with a purity greater than 99%, capable of withstanding temperatures up to 1750°C, and is used to support, hold, or contain materials during high-temperature processes.
The complete set of kiln furniture typically consists of trays and columns, designed reasonably based on factors such as the size of the muffle furnace chamber and the quantity of samples to be processed.
The alumina trays are double-side ground for high flatness and excellent chemical resistance. They are commonly used in processes such as sintering, firing, and annealing in ceramics, metallurgy, glass production, and materials science.
Alumina trays are available for purchase separately.

Applications :
Support and Stability: Used to support and secure samples or kiln furniture, ensuring stability during high-temperature processes.
Enhanced Heat Circulation: Helps improve heat circulation within the furnace, increasing thermal conduction efficiency and ensuring uniform heating.
Multi-Layer Configuration: Enables multi-layer structures to optimize furnace space, improving processing efficiency and accommodating multiple samples or large quantities of material.
Chemical Stability: High-purity alumina offers excellent chemical stability, making it suitable for high-temperature environments and reducing the risk of contaminating samples.
High-Temperature Resistance: Capable of withstanding temperatures up to 1750°C, ideal for ceramic sintering, metal refining, and other high-temperature processes.
Flexibility and Customization: Can be customized to meet specific application requirements, offering a range of sizes and shapes to suit various experimental and industrial needs.
Precautions for Using Alumina Kiln Furniture:
Avoid Rapid Temperature Changes: To prevent cracking or damage from thermal shock, avoid sudden temperature changes. Both heating and cooling should be done gradually.
Proper Loading: Ensure that samples and kiln furniture are evenly distributed to avoid overloading or imbalance, allowing for uniform heating and prolonged kiln furniture lifespan.
Prevent Chemical Reactions: Avoid contact between alumina kiln furniture and strong acids, alkalis, or other reactive chemicals to prevent corrosion or sample contamination.
Regular Inspection: After extended use at high temperatures, regularly inspect the kiln furniture for cracks, wear, or deformation, and replace any damaged pieces promptly.
Cleaning and Maintenance: Clean the kiln furniture after use to remove any residues or impurities, ensuring they don’t affect the next experiment or production process.
Temperature Limits: Ensure that the kiln furniture is used within its designated temperature range, typically up to 1750°C, to prevent failure or degradation of its performance.
Proper Equipment Fit: Choose kiln furniture that matches the size and design of the muffle furnace or other high-temperature equipment to optimize performance and efficiency.
