| CR-EL | |
|
CR-EL is ISK's standard grade manufactured by the chloride process. The particle size of this grade is ca. 0.25μm which is the same size as conventional white pigment. CR-EL shows excellent dispersibility and reactivity. Moreover, consistency of the quality has been achieved, which has made it suitable for electronic ceramic applications. |

|
| PT-301 | |
|
PT-301 is a higher purity grade with the same particle size compared to CR-EL. It is also manufactured by the chloride process. This grade shows as excellent dispersibility and reactivity as CR-EL, and it is suitable for electronic ceramic applications which especially require high purity. |

|
| PT-401M | ||
|
PT-401M is a high-purity titanium dioxide with small particle size, which is manufactured by the chloride process. This grade shows as excellent dispersibility and reactivity as CR-EL, and it is suitable for electronic ceramic applications which especially require fine particles. |
