Alumina Ceramic Evaporating Crucible Dish 50-1000ml Glazed Porcelain Evaporating Dish with Spout

Overview of Alumina Dish

An Alumina Dish is a ceramic dish made primarily from alumina (Al₂O₃), a highly durable and heat-resistant material derived from aluminum oxide. Alumina dishes are known for their strength, resistance to high temperatures, and electrical insulating properties. Due to these characteristics, alumina dishes are commonly used in various laboratory and industrial applications. Alumina is one of the most commonly used materials in high-performance ceramics because it exhibits excellent wear resistance, chemical stability, and electrical insulation properties.

Features of Alumina Dish

1. High-Temperature Resistance: Alumina dishes can withstand very high temperatures (typically up to 1,600°C or more), making them ideal for use in high-temperature environments such as laboratories or industrial furnaces.
2. Chemical Inertness: Alumina is chemically inert, meaning it does not react with most acids, bases, or solvents. This makes alumina dishes suitable for use with reactive chemicals.
3. Mechanical Strength: Alumina dishes are known for their excellent mechanical properties. They are strong and resistant to wear, crack, and breakage, which enhances their durability in harsh conditions.
4. Electrical Insulation: Alumina has good electrical insulating properties, which is particularly important for applications involving electrical components or circuits.
5. Thermal Conductivity: Although alumina is a good insulator, it also offers controlled thermal conductivity, making it effective in applications where heat needs to be distributed evenly.
6. Surface Smoothness: The surface of alumina dishes is usually very smooth, making them easy to clean and resistant to contamination.
7. Non-Toxic: Alumina is non-toxic and food-safe in its pure form, though this depends on the specific application (e.g., if the dish is used in contact with food or chemicals).

FAQs about Alumina Dish

1. What is an alumina dish made of?
   • An alumina dish is made primarily from alumina (Al₂O₃), a ceramic material derived from aluminum oxide. It is highly resistant to heat, wear, and chemicals.
2. What are the temperature limits for an alumina dish?
   • Alumina dishes can generally withstand temperatures up to 1,600°C (2,912°F), but the exact temperature limit can vary depending on the specific grade of alumina used.
3. Can alumina dishes be used for food preparation?
   • Alumina dishes are generally non-toxic and food-safe in their pure form, but they are more commonly used in laboratory or industrial settings. If you plan to use them in food preparation, ensure they are specifically labeled as food-safe.
4. Are alumina dishes durable?
   • Yes, alumina dishes are known for their mechanical strength and durability. They are resistant to breakage, wear, and corrosion, making them long-lasting in harsh environments.
5. How do I clean an alumina dish?
   • Alumina dishes can be cleaned with mild detergents and water. For tougher stains, use a non-abrasive cleaner. Avoid using harsh chemicals that might damage the surface or compromise its properties.
6. Are alumina dishes chemically resistant?
   • Yes, alumina is highly chemically resistant, making these dishes suitable for use with many acids, bases, and solvents without degrading or reacting with the substances.
7. Can alumina dishes be used in microwave ovens?
   • While alumina dishes are used in some microwave applications due to their dielectric properties, it is important to confirm that a particular alumina dish is microwave-safe before use. Standard alumina dishes designed for laboratory or industrial purposes may not be suitable for microwaving food.
