Abstract
A synthesis method for producing a refractory oxide-ceramic material of CaZrO3, in particular in the form of a refractory granular material that is preferably mechanically comminuted, in particular crushed and/or ground, as well as to a batch and a coarse ceramic, shaped or unshaped, refractory product containing at least one pre-synthesized refractory calcium zirconate-containing granular material.
Claims38
A synthesis method for a synthesis of a refractory oxide-ceramic, calcium zirconate-containing material, having the following method steps:
- a) producing a mixture of at least one mealy Ca raw material component, at least one mealy ZrO2 raw material component, and water, wherein a molar ratio of CaO/ZrO2 in the mixture is 1.5:1 to 1:1.6,
- b) pressing the mixture to form at least one green shaped body,
- c) sintering the at least one green shaped body,
- wherein the mixture that is produced from step a) consists exclusively of the at least one mealy Ca raw material component, the at least one mealy ZrO2 raw material component and water, and the mixture that is produced from step a) comprises a water content of more than 5 wt. % and equal or less than 10 wt. % relative to a dry mass of the mixture that is produced from step a).
