Product Description

Alumina Microwave Magnetron Ceramic / Ceramic Rod for Home Electrical Appliances

 

1. Description:

Alumina microwave magnetron ceramic containing more than 95% Al2O3 is commonly referred to as high alumina ceramic.
95% alumina ceramic is one of the most widely used structural ceramics.Because of its excellent electrical properties at high frequency,
95% alumina ceramic has small dielectric loss, large volume resistivity, high strength, hardness, small linear expansion coefficient, and good abrasion resistance and heat resistance.95% alumina ceramic is more economical and practical to use for ordinary circumstances.For occasions where performance requirements are particularly high, 99% ~ 99.9% alumina ceramic is used.

 

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision

7) High stability

8) Good advanced ceramic materials

9) High welding sealing performance

10) High hardness and high density

11) Low thermal conductivity

12) Chemical inertness

13) Good wear resistance

14) High Fracture toughness

15) Good insulation performance

16) High temperature resistance
