Advantage：
Advantages:
1)High purity and superior function.
2)Good flateness and high precision in size.
3)Strong production capacity.
4)High qualification rate.
5) There are no fragile plates because we use high strength alumina ceramic.
Application:
★ Laboratory analysis and various industrial analysis, metal and nonmetal material sample melting.
Composition:
Alumina content ranges from 60% to 99.9%, with higher purity grades (e.g., 99.7%) offering superior hardness,thermal stability, and electrical insulation.
Thermal Resistance:
Withstands temperatures up to 1650°C, making them ideal for high-temperature applications like furnace tubes and thermocouple insulation.
Mechanical Strength:
High compressive strength (~2500 MPa) and Vickers hardness (11-14 GPa) ensure durability in abrasive environments.
Electrical Insulation:
