Изобрете1Ы1е относитс  к производству молибдата инди , который может быть иснользован дл  получени  монокристаллов.The invention relates to the production of indium molybdate, which can be used to produce single crystals.

Известен способ получени  молибдата инди  путем осажденп  из водпых растворов соли инди  н нормального молибдата одновалс 1тно1-о катиона. Недостатком известного способа  вл етс  то, что получают молибдат ппдн  нестехиометрического состава.A known method for producing indium molybdate by precipitating from aqueous solutions of an indium normal molybdate salt is one to one of a single cation. A disadvantage of the known method is that molybdate is prepared with a non-stoichiometric composition.

С целью получени  стехпометрического конечного продукта нредложено в качестве исходных продуктов использовать хлорид инди  п молибдат натри , а процесс вести при значеппи рН раствора, равном 3,2-3,5. При этих услови х образующийс  молибдат инди  имеет состав Ьп2(МоО4).In order to obtain a stokhpometrichesky final product, it is proposed to use indium sodium molybdate chloride as the starting products, and the process should be carried out with a pH of 3.2-3.5. Under these conditions, the resulting indium molybdate has the composition bn2 (MoO4).

Пример. 2л 0,2 М раствора хлорида инди  с рН 3,0-3,3 но капл м приливают к 3 лExample. 2 l of 0.2 M indium chloride solution with pH 3.0-3.3 but added dropwise to 3 l

0,2 М раствора молпбдата натри  с рН 6,0-6,2 п интенсивно перемешивают в течение 1 час. После 1 час отстаивани  осадок отфильтровывают, промывают 1 л подкисленной воды с рЫ 3,35 н сушат при 40°С до поСТОЯ1ПЮГО веса.A 0.2 M solution of sodium molpbdate with a pH of 6.0-6.2 p is vigorously stirred for 1 hour. After 1 hour of settling, the precipitate is filtered off, washed with 1 l of acidified water from a PRE 3.35 n, dried at 40 ° C to a steady weight.

Выход продукта 55% от теоретического.The product yield is 55% of the theoretical.

Предмет изобретени Subject invention

Способ получени  среднего молибдата инди  путем осалчденн  нз водных растворов соли индн  н нормального молибдата одновалентного катиона, отличающийс  тем, что, с целью получени  стехиометрического конечного продукта, в качестве исходных продуктов используют хлорид инди  и молшбдат натри , а процесс ведут при значении рН раствора , разном 3,2-3,5.The method of obtaining average indium molybdate by means of osalcidns in aqueous solutions of a salt of an indi n normal molybdate monovalent cation, characterized in that, to obtain a stoichiometric final product, indium chloride and sodium molshbdat are used as starting products, and the process is carried out at a pH value of the solution that 3.2-3.5.
