Detailed Product Description

Electronic Ceramic Components / Ceramic Electronic Parts

 

1. Description:

Resistivity ρ of BaTiO3 ceramics sintered in reducing atmosphere (oxygen partial pressure of 2 × 10−12 MPa) was not degraded by doping CaO when A/B ratio m was over unity. Essential points in the composition designing are 1) control of the molecular ratio (Ba + Ca)O/(Ti Zr)O2 larger than unity, 2) incorporation of Ca ions into Ti lattice site (B site) of BaTiO3, and 3) doping acceptor as Mn ions. Mg ions have the same effect as Ca ions.

 

2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Chemical inertness

4) Good wear resistance
