Abstract

A lead molybdate nano crystal material and a preparation method thereof are disclosed. The preparation method comprises following steps: respectively dissolving sodium chromate, lead nitrate and sodium molybdate in deionized water to prepare a sodium chromate solution, a lead nitrate solution and a sodium molybdate solution, mixing the sodium chromate solution with the lead nitrate solution according to the mole ratio of CrO4<2-> to Pb<2+> of 1:1, obtaining a solution containing the lead chromate precipitation, then mixing the sodium molybdate solution with the solution containing the lead chromate precipitation according to the mole ration of MoO4<2-> to Pb<2+> of 1:1, standing for 3 to 10 hours, filtering to obtain the precipitation generated by the reactions, repeatedly washing the precipitation with deionized water and absolute ethanol, and then drying the precipitation so as to obtain the product. The preparation method produces a lead molybdate nano crystal material, which has good crystallinity, high purity and a high length-diameter ratio. The material has vast application prospects in the fields of acousto-optic devices, optical fibers, optical materials and photocatalyst.

Description

technical field

[0001] The invention relates to an inorganic non-metallic nano crystal material, in particular to a lead molybdate nano crystal material and a preparation method thereof. Background technique

[0002] Lead molybdate is a new type of material with scheelite structure. It has high practical value in laser radar, scanning of TV and large-screen display, optical memory of photonic computer, laser communication and nuclear equipment. A photocatalyst, luminescent material and optical fiber, also has very broad application prospects.

[0003] The traditional method for preparing lead molybdate is a solid-state reaction method. Although this method has a simple process, it often requires high-temperature heat treatment, high energy consumption, and the prepared product has low purity and is easy to agglomerate, so it is difficult to control the grain size. size and shape. Contents of the invention

[0004] In order to solve the problems of low purity, easy ag...
