摘要：
Disclosed are dielectric porcelain materials having compositions falling in the quadrilateral area defined by connecting points A, B, C and D in the ternary diagram of components Al.sub.2 O.sub.3, CaTiO.sub.3 and SrTiO.sub.3 in the drawing. The points A, B, C and D are represented in mol % as follows:______________________________________ Al.sub.2 O.sub.3 CaTiO.sub.3 SiTiO.sub.3 ______________________________________ A 0.99 0.01 0 B 0.96 0.035 0.005 C 0.91 0.04 0.05 D 0.91 0.01 0.08. ______________________________________ The dielectric porcelain materials have thermal coefficients between -15 and +15 and a no-load Q not less than 4000.
