  • Method for manufacture of transparent ceramics
    Patent number: 7799267
    Abstract: The disclosed invention relates to a method of manufacture of transparent ceramics such as yttrium aluminum garnet by tape casting. The method entails forming a mixture of ceramic oxide, dispersant and organic solvent, milling the mixture to produce a first slurry, mixing the first slurry with an organic binder and a plasticizer to form a treated slurry, milling the treated slurry to produce milled slurry, tape casting the milled slurry to produce cast tape, drying the cast tape to produce dried tape, stacking portions of dried tape to form an assembly, compressing the assembly to produce a preform, heating the preform to produce a green preform, and sintering the green preform to produce transparent yttrium aluminum garnet. The method may be used to produce a unitary ceramic product having differing transparent sections as well as transparent ceramic product having a dopant gradient across a portion of the thickness of the product.
    Type: Grant
