Product Description

Electronic Ceramic Components / Ceramic Electronic Parts

 

1. Description:

Electronic ceramics with a long history of technological applications in the ceramic capacitor industry. The Ti-rich region (>50% TiO2) of the BaO–TiO2 gives few compositions which exhibit [1–6] good temperature compensation with very good relative permittivity and low dielectric loss at radio frequencies. In 1947, Bunting and co-workers reported [1, 2] a low-loss temperature-compensated composition containing 83.3 mol% TiO2 with ɛr = 37 at 1 MHz.

 

2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Chemical inertness

4) Good wear resistance

5) High Fracture toughness

6) Good insulation performance

7) High temperature resistance

8) A variety of specifications is available

9) Satisfy various technical requests

10) Lower medium spoilage

11) Stiffness texture

12) Chemical inertness

13) Good wear resistance

14) High Fracture toughness

15) Good insulation performance
