Grain growth in TiO2-added ZnO-Bi2O3-CoO-MnO ceramics prepared by chemical processing

Toplan, Hüseyin Özkan (ELSEVIER SCI LTD, 2002)

The effect of TiO2 on the grain growth of the ZnO-Bi2O3-CoO-MnO ceramic system prepared by chemical coprecipitation, was studied between 1150 and 1300 degreesC in air. Bi2O3 melts during firing, and then TiO2 dissolves ...
Processing and phase evolution in low voltage varistor prepared by chemical processing

Toplan, Hüseyin Özkan (ELSEVIER SCI LTD, 2001)

A new chemical process has been developed to form a low voltage varistor. The chemistry of process has been analysed and used to produce particles consisting of an intimate mix of ZnO, Zn2TiO4 and beta -Bi2O3 phases. The ...
