Notes:
The dielectric ceramics of CaTiSiO5-CaTiO3 with ZnO and B2O3 as additives were sintered at950ºC. Of the ceramics with a small quantity of 2ZnO-B2O3 as the additive, the density is nearly the sameas the one reported, εr= 83 ~ 99, tgδ 〈 7×10-4, αε= (-100~+100) ppm/ºC. The crystal phases and microstructuresare analyzed by X-ray diffraction and scanning electron microscope. It is found that the sinteredceramics is of biphase, comprising monoclinic CaTiSiO5 and orthorhombic CaTiO3, and the grains aremostly the small circular ones, having diameters of 1~29m. By adjusting the composing of the ceramic, ahigh frequency dielectric ceramic CaTiSiO5-CaTiO3, of which αε= (-50~+50) ppm/ºC was attained
