1. High Temperature Resistance: Alumina ceramics can withstand extremely high temperatures, often exceeding 1700°C, making them ideal for use in high-temperature environments like furnaces and kilns. 2. Excellent Wear Resistance: Due to their hardness, alumina ceramic tubes and pipes are highly resistant to abrasion, which extends their lifespan significantly in applications involving high wear. 3. Chemical Inertness: Alumina ceramics are chemically inert to most acids, alkalis, and solvents, making them suitable for use in corrosive environments without degrading. 4. Electrical Insulation: Alumina ceramics tubes have excellent electrical insulation properties, making them ideal for use in electrical and electronic applications where high insulation is required. 5. High Mechanical Strength: Alumina ceramics tubes have high compressive strength, which allows them to withstand mechanical stress and pressure in demanding applications. 6. Low Thermal Conductivity: Alumina ceramic tubes and pipes have low thermal conductivity, which makes them useful for applications that require thermal insulation.

1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%. 2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color. 3. Alumina is a refractory material, the higher the purity, the better the refractory effect 4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
