amp;beta;-EUCRYPTITE CERAMIC HAVING ZERO EXPANSION COEFFICIENT, HIGH STRENGTH AND LOW DIELECTRIC CONSTANT

摘要

PROBLEM TO BE SOLVED: To provide a β-eucryptite ceramic which has a zero expansion coefficient, high strength and a low dielectric constant, and is sintered at low temperature.;SOLUTION: The β-eucryptite ceramic sintered compact which has a zero expansion coefficient, high strength and a low dielectric constant is obtained by sufficiently mixing the raw material powder composed of a composition of β-eucryptite ceramic, calcining the mixture at low temperature, adding a sintering assistant thereto, and pulverizing the same.;COPYRIGHT: (C)2012,JPO&INPIT
