Customize High Temperature Industrial 95% 99% Al2O3 Alumina Ceramic Plate
Alumina ceramic plates are a type of advanced ceramic material widely used in various industrial applications due to their excellent mechanical, thermal, and electrical properties. Here's an overview of the key characteristics, applications, and benefits of alumina ceramic plates:
Characteristics
Applications
Benefits
Types and Grades
Alumina ceramics come in various purities and grades, commonly ranging from 85% to 99.9% alumina content. Higher purity grades offer better performance in terms of electrical insulation and thermal conductivity but may be more expensive.
Customization and Manufacturing
Alumina ceramic plates can be custom-manufactured to specific dimensions and shapes to meet the requirements of different applications. They can also be processed to achieve varying surface finishes and tolerances, depending on the need.
