La- and Ca-modified BaTiO3-Ba6Ti17O40 eutectics have been examined in
a heating microscope. Using video equipment the heights of the eutecti
c powder-tips on BaTiO3 substrates were measured and analysed. The cor
responding plots of heights vs. heating time allow the objective estim
ation of the onset temperatures of melting processes and the detection
of additional liquid phases. Preliminary findings obtained with this
method are presented.
