99% High-Purity Alumina Firing Plate Description: High-Purity Alumina Firing Plate is a premium ceramic plate made from 99% pure alumina, designed for use in high-temperature muffle furnaces. Known for its excellent thermal resistance, chemical stability, and strength, it can withstand temperatures up to 1700°C or higher, making it ideal for processes like sintering, calcination, and material testing. Its high purity ensures minimal contamination, providing a clean and stable environment for precise heating and material processing. Durable and resistant to thermal shock, this firing plate is perfect for both industrial and laboratory applications requiring reliable, high-temperature solutions. Dimensions: 105×105×12mm Wall Thickness: 5mm Alumina Purity: >99% Continuous operating temperature: ≤1600°C Alumina Firing Plate is available in both footed and flat designs. Multiple plates can be stacked or combined to form a complete furnace set. We offer customized services according to your requirements!

Before the first use, preheat the alumina plate in an oven at around 105°C for 120 minutes to remove moisture. 2. Do not directly heat the alumina plate with gasoline blowtorch, acetylene torch, or alcohol burner to avoid uneven heating and cracking of the product. 3. The heating or cooling rate should not be too fast. The temperature change below 1200°C should be <5°C/minute, and above 1200°C should be ≤4°C/minute. 4. The distance between the product and the heating element (such as carbon tube, silicon molybdenum rod, or heating wire, etc.) should be >2cm. 5. The bottom of alumina plate should preferably not directly contact the bottom of the furnace. It is recommended to use alumina foot pads or other heat-resistant materials to lift the alumina plate, forming air convection to prolong the service life of the product.
