  • FIRING AID COMPOSED OF A COMPOSITE MATERIAL, COMPOSITE MATERIAL AND METHOD OF PRODUCTION THEREOF, AND USE THEREOF
    Publication number: 20240116804
    Abstract: A formulation usable to produce plates and shaped bodies has a base slip, quartz glass particles and multicomponent glass particles that are crystallizable or at least partly crystallized. The base slip contains water as dispersion medium with a content between 30% and 50% by weight and ultrafine SiO2 particles distributed, preferably colloidally therein, with a proportion between 50% and 70% by weight. The proportion of quartz glass particles in the formulation is in the range from 40% to 70% by weight and the proportion the multicomponent glass particles in the formulation is in the range from 5% to 37% by weight. The formulation can be used in a composite material. Firing aids can be made from the composite material.
