(Zr, Sn)TiO4 powders were prepared in 0.05~0.13 ${mu}{ extrm}{m}$ by coprecipitating (Zr4+, Ti4+)hydroxide on SnO2 particles and followed by calcination at 90$0^{circ}C$ for 2 h. They sinter to 95% of relative density at 140$0^{circ}C$ for 2 h. and shows dielectric constant, $varepsilon$r=37.5 and quality factor, Qxf(GHz)=46,000. With 3 mol% of ZnO it sinters to rel=97.5%, $varepsilon$r=39 and Qxf(GHz)=40,050 at 135$0^{circ}C$ for 2 h., but raising sintering temperature to 140$0^{circ}C$ deteriorates quality factor, relative density and microstructure with developing second phase.
