Non-aqueous tape casting method for preparing laminar composite transparent ceramic
The present invention provides a non-aqueous tape casting method for preparing a laminar composite transparent ceramic. The method comprises the following steps: material preparation is performed; a raw material is subjected to wet process ball-milling with an oil-soluble organic solvent as a ball-milling medium and then is subjected to vacuum defoamation so as to obtain a casting material; the casting material is subjected to casting, wherein the height of a casting knifeedge is controlled within 0.001-3mm, and casting sheets are obtained; the several casting sheets are subjected to laminated warm-pressing composite formation to obtain a composite compact body; after glue is discharged, the temperature of the composite compact body is raised to the organic substance decomposition temperature at a speed of 0.01-50 DEG C/min to obtain a composite green compact; the composite green compact is subjected to one-time temperature-raising sintering or fragmented temperature-raising sintering, and is annealed at 1000-1600 DEG C to the laminar composite transparent ceramic. The non-aqueous tape casting method for preparing the laminar composite transparent ceramic provided by the invention effectively solves a difficult problem of the fragility of a transparent ceramic panel.
