Plasma Spraying as a Technique for Dielectric Ceramics Preparation
Ctibor, Pavel ; Rohan, Pavel ; Kolman, Blahoslav Jan ; Dubský, Jiří ; Chráska, Pavel
This paper reports on plasma spraying of several synthetic titanetes.Ceramic materials CaTiO3-LaMg0,5Ti0,5O3,Zr0, 8Sn0,2TiO4 as well as mixture of geikielite-perovskite MgTiO3-CaTiO3 were sprayed using gas stabilized plasma gun.These materials are well know as microwave dielectrics. Plasma spraying was performed with the gas stabilized plasma gun Plasmatechnik HB4.Standard experimental techniques were used for studying of microstructure, chemical and

Electric Resistivity of Plasma Deposited Titanates
Ctibor, Pavel ; Sedláček, J.
This work representes first output from a broader study of dielectric properties of plasma deposits made from powder with the same starting composition as industrially produced dielectric ceramics.Influence of plasma spraying itself and of the subsequent annealing of sprayed deposits on electric resistivity of several titanates is reported here.Only a small number of papers exist about the dielectric properties of thermally sprayed deposits,but on the
