Product Details
ZYLAB ceramic alumina plates with holes are ground on all six sides, offering excellent heat resistance, corrosion resistance, and high flatness. They are commonly used in high-temperature experiments as reaction containers, isolation materials, or support plates for sample materials.
The perforated design helps maintain gas flow during heating or reactions, making them ideal for experimental equipment that requires gas circulation, such as muffle furnaces and controlled atmosphere furnaces, ensuring sufficient gas contact or ventilation with the samples.
Alumina Purity: >99%
Maximum temperature resistance: 1750°C
Continuous operating temperature: ≤1600°C

Use Alumina Plates with Holes
1. Before the first use, preheat the crucible in an oven at around 105°C for 120 minutes to remove moisture.
2. Do not directly heat the crucible 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 large crucibles 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 crucible, forming air convection to prolong the service life of the product.
