The technology of electronics has shown very remarkable progress and electronic devices such as cellular phones and personal computers have become more and more popular. High performance, high accuracy and the miniaturization of those electronic devices have been eagerly required.

ISK has supplied high-purity titanium dioxides as raw materials of ceramic capacitors, noise filters and so on which are used in those electronics devices.

Main Applications

○Raw materials for dielectric materials such as barium titanate and PZT as electronic ceramics for capacitors, piezoelectric devices and thermistors.

○Raw materials for structural ceramics. 

１．Properties of High-Purity Titanium Dioxide, CR-EL and PT series

• Various grades depending on purity and particle size.   (Click here for Grade List) 

• Narrow particle size distribution 

Table 1. Grade Classification by Particle Size and Purity

Fig. 1  Relationship between particle size and thermal shrinkage

 As in this figure, titanium dioxide grades with higher purity and/or smaller particle size start to shrink at relatively lower temperature.                   

 Thus the purer and smaller grades can be expected to show higher reactivity in the synthesis of complex oxides such as barium titanate.
