Alumina Ceramic

Advantages of 99.3% Alumina Ceramic Rod

Alumina ceramic rods can withstand high temperatures up to 1650 ℃, 20—1000℃ coefficient of thermal expansion(8.2 × ㎜.10-6／℃.m), and can maintain dimensional stability even in environments with sudden temperature changes Capable of withstanding rapid temperature rise and fall processes, suitable for intermittent temperature measurement experiments.

Applications of 99.3% Alumina Ceramic Rod

1. High temperature furnace: Due to its heat resistance, 99.3% alumina ceramic rods are commonly used in industrial furnaces and heating elements.

2. Electrical insulation: Alumina ceramic rods are used as insulation components in high-voltage environments and electronic devices.

3. Chemical processing equipment: The chemical resistance of alumina ceramic rods makes them suitable for processing corrosive substances in the chemical industry.

4. Wear resistant components: In industries prone to wear, alumina ceramic rods are used as wear-resistant components to extend the lifespan of machinery.

5. Mechanical seals and shafts: The excellent hardness and low friction performance of alumina ceramic rods make them an ideal choice for mechanical seals, pumps, and shafts used in harsh environments.
