Process of making ceramic moldings containing cordierite

摘要: Ceramic moldings containing finely crystalline cordierite are described, which obtainable by the intensive grinding of precrystallized powder, mixing powder with second additive phases higher modulus elasticity, shaping mixture, and sintering greenware thus obtained in a siliceous atmosphere at temperatures between 900° 1400° C. The according to invention have not only good mechanical strengths but also outstanding dielectric thermal properties; they therefore especially suitable for use as dielectrics insulating components.
