Alumina ceramics are the most common advanced ceramic material and more traditional. As an excellent ceramic material, high purity alumina ceramics have been widely used in many industries. The material has excellent properties in terms of electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Therefore, alumina ceramic products are ideal for many industries such as:

• Shafts and plungers in high wear environments
• Roller and ball bearings
• Wear-resistant lining
• semiconductor part
• Machine components
• High temperature electrical insulators
• High-voltage insulators
• Wires and conductors
• mechanical seal

Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is one of the most commonly used high grade ceramics. Zhihao Ceramics offers alumina ceramics with purity ranging from 95% to 99.5%.

• Excellent electrical insulation (1×10¹⁴to 1×10¹⁵ (Ω cm);
• Medium to ultra-high mechanical strength (300 to 630 MPa);
• Very high compressive strength (2000 to 4000 MPa);
• High stiffness (15 to 19 GPA);
• Medium thermal conductivity (20 to 30 W / MK);
