Exceptional Thermal and Chemical StabilityAlumina Crucibles, Dishes, and Trays offer impressive thermal shock resistance and maintain structural integrity during rapid heating and cooling cycles. Their high maximum operating temperature (up to 1750C) and robust chemical resistance ensure reliable performance in laboratories conducting high-temperature reactions or working with aggressive reagents.
Customizable Shapes and Sizes for Versatile ApplicationsWhether you need cylindrical, rectangular, or square forms-deep or shallow-these alumina wares are manufactured in a range of wall thicknesses (1-5 mm) and sizes (5 ml to 500 ml, or custom). This adaptability ensures a precise fit for each application, from sample ashing and melting to intricate chemical analyses.
Durable and High-Purity ConstructionManufactured via isostatic pressing and high-temperature sintering, these products possess high compressive strength (>2500 MPa) and a dense, gas-tight structure to preserve sample integrity. With a purity of 99.7% minimum, they provide contamination-free results for analytical and technical-grade laboratory work.
FAQ's of Alumina Crucibles, Alumina Dish, Alumina Tray:
Q: How do alumina crucibles withstand rapid temperature changes without cracking?
A: Alumina crucibles exhibit excellent thermal shock resistance due to their low thermal expansion coefficient and advanced manufacturing process. This allows them to endure fast transitions between high and low temperatures without fracturing, making them suitable for dynamic heating applications.
Q: What types of chemicals are alumina trays and dishes resistant to during laboratory use?
A: Alumina trays and dishes are resistant to most acids, alkalis, and organic solvents. Their exceptional chemical stability preserves the purity of your samples and extends the lifespan of the ware, even in aggressive chemical environments.
Q: When should I choose alumina crucibles over other materials for laboratory applications?
A: Choose alumina crucibles when your application requires high-purity sample handling, exposure to extreme temperatures (up to 1750C), or resistance to corrosive chemicals. They are ideal for sample ashing, melting, alloy production, and analytical testing in rigorous environments.
Q: Where can customized sizes and shapes of alumina crucibles, dishes, and trays be obtained?
A: Custom sizes, volumes, and shapes-ranging from 5 ml to 500 ml and beyond-are available directly from the manufacturer, supplier, or trader. These options allow you to select the perfect fit for your specific experimental setup or industrial process.
Q: What process is used to manufacture alumina crucibles, dishes, and trays?
A: These products are made by isostatic pressing and sintering at high temperatures. This technique results in a dense, robust ceramic structure with a gas-tight finish, ensuring consistent quality, strength, and purity.
Q: How should alumina laboratory ware be stored to maintain its properties over time?
A: To retain their superb characteristics, alumina crucibles, dishes, and trays should be stored in a dry, cool location with the container tightly closed. Following these guidelines preserves their indefinite shelf life.
Q: What are the main benefits of using high-purity alumina crucibles, dishes, and trays in research and industry?
A: High-purity alumina laboratory ware ensures contamination-free results, exceptional durability under thermal and mechanical stress, outstanding chemical resistance, and versatility in application. These qualities make them indispensable tools in research, analytical testing, and high-temperature industrial processes.
