Alumina Dish
Alumina dish is a laboratory tool made from alumina (aluminum oxide, Al₂O₃), a ceramic material known for its high thermal and chemical stability. It is commonly used in high-temperature applications, such as heating, melting, or calcining samples.
Key Features:
- High-Temperature Resistance: Alumina can withstand extremely high temperatures, often up to 1700°C (3092°F) or more, making it suitable for use in furnaces and other high-heat environments.
- Low Thermal Conductivity: Alumina has relatively low thermal conductivity, which helps in maintaining uniform heating and reducing heat loss
- Mechanical Strength: Alumina boat crucibles are durable and can withstand physical stress, making them reliable for repeated use.
- Thermal Shock Resistance: They have good resistance to thermal shock, meaning they can endure rapid temperature changes without cracking.
