A preparation method of an
yttrium vanadate transparent
ceramic comprises the following steps: dissolving
yttrium nitrate hexahydrate in deionized water at first, magnetically stirring to obtain an
yttrium nitrate aqueous solution, then adding a proper amount of
citric acid and
ammonium metavanadate, and magnetically stirring to obtain a
mixed solution; placing the
mixed solution in an oven and evaporating to remove water so as to obtain a brown
solid product, breaking the product and then annealing the product in a
muffle furnace, and washing and
drying the product with dilute
nitric acid anddeionized water to obtain yttrium
vanadate nano
powder; and finally carrying out
dry pressing forming on the obtained yttrium
vanadate nano
powder, and
sintering in a pressure-free manner in an
air atmosphere to obtain the yttrium vanadate transparent
ceramic. The yttrium vanadate
ceramic prepared by the invention is high in compactness and good in light transparency, and moreover, the method hasthe advantages of low
sintering temperature, simple preparation process, short production period, low cost and the like, and is suitable for industrialized production of a yttrium vanadate transparent ceramic material.
