Specialized Alumina Sintering Platform for Laboratory Research
Introduction:
The alumina sintering platform is a platform made of high-purity alumina for placing crucibles, characterized by extremely high purity and excellent physical and chemical properties.
Compared to alumina sintering plates, it features a four-corner support structure, which facilitates air convection, extending the product’s lifespan.
Widely used in materials science research and laboratory settings, the alumina sintering platform can be employed for sample preparation, heat treatment testing, and other applications.
Manufacturing Process:
1、Making abrasives
2、Making blanks
3、Firing blanks
4、Storage after passing inspection
Advantages:
1. The product material is 95% alumina (Al2O3 > 95%), with high purity.
2. Adopting slip casting/pressing molding process.
3. Firing temperature is 1800°C, long-term use temperature ≤ 1600°C.
4. High temperature resistance and chemical corrosion resistance.
Product Specifications:
100*100*15mm

Alumina Crucible Usage Precautions:
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. When cooling, it is recommended to control the temperature by powering off gradually. Cooling too fast during the initial cooling phase after turning off the power may cause the product to crack.
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.
