Custom 99 Porcelain Alumina Special - Shaped Insulating Ceramic

Product Overview

Alumina ceramics have many excellent properties, so they are widely used in the world. Alumina ceramics have a Vickers hardness of 15GPa, a density of about 3.75g/cm3, a compressive strength of about 2100MPa, a flexural strength of 300Mpa, a volume resistance of 1014Ω·m, an expansion coefficient similar to that of metals, and good chemical stability.

High-frequency insulating ceramics, also known as device ceramics, are used in electronic equipment to install, fix, and protect components, as insulating supports for current-carrying conductors, and as ceramics for various integrated circuit substrates. Small dielectric constant, low dielectric loss, high mechanical strength, and high dielectric strength, insulation resistance and thermal conductivity. Commonly used high-frequency insulating ceramics include high-alumina porcelain and talc porcelain.

Product advantages

• Size and thermal stability
• High performance features
• Hydrolysis resistance
• Self-lubricating performance
• Extended service life

Alumina ceramic material has good insulation, otherwise, stainless, strong and not easy to damage, and has the same excellent properties as other organic materials and metal materials. The production process of alumina ceramics includes five steps: calcination, batching, fine grinding, shaping and sintering.
