摘要： An object of the invention is to provide a dielectric porcelain composition with low rate of phase change of a cordierite phase as a primary crystal phase, in which as a result of the low rate of phase change the dielectric constant is from 4.5 to 6 and Q value is 1,000 or more at 60 GHz, and to provide a dielectric resonator and nonradiative dielectric strip using the same. The dielectric porcelain composition comprises, as a principal component, a complex oxide having a molar composition xMgO·yAl2O3·zSiO2 (wherein 10≦x≦40, 10≦y≦40, 20≦z≦80 , and x+y+z=100), and a ratio of a (241) peak intensity &bgr;p(241) and a (222) peak intensity &bgr;p(222) of X-ray diffraction of a &bgr; phase of a 2MgO·2Al2O3·5SiO2 phase, which is a primary crystalline phase of the complex oxide, is 0.8≦&bgr;p(241)/&bgr;p(222)≦1.3.

摘要： A method of making polycrystalline magnesium orthosilicate including the steps of contacting a silica based clay material with magnesium oxide; and sintering the magnesium oxide contacting the silica based clay material to cause a solid state diffusion of the magnesium oxide into the silica based clay material to thereby produce polycrystalline magnesium orthosilicate. Single crystalline magnesium orthosilicate can be made by melting under controlled conditions, the polycrystalline magnesium orthosilicate.
