Embodiment 1

[0015] Weigh 600 g of selenium dioxide and add it to 2 L of water to dissolve. After the dissolution is complete, add 430 g of zinc oxide and stir. After the reaction is completed, it is washed, dried and pulverized to produce zinc selenite product.

Embodiment 2

[0017] Weigh 500 g of selenium dioxide and add it to 1.5 L of water to dissolve. After the dissolution is complete, add 400 g of zinc oxide and stir. After the reaction is completed, it is washed, dried and pulverized to produce zinc selenite product.

Embodiment 3

[0019] Weigh 700 g of selenium dioxide and add it to 2.5 L of water to dissolve. After the dissolution is complete, add 500 g of zinc oxide and stir. After the reaction is completed, it is washed, dried and pulverized to produce zinc selenite product.

Abstract

The invention discloses a zinc selenite production method, which comprises the following steps: step one, 500 to 700 g of selenium dioxide is weighed, added into 1.5 to 2.5 L of water, and stirred to lead the selenium dioxide to be completely dissolved in the water; step two, the selenium dioxide water solution obtained in step one is added with 400 to 500 g of zinc oxide, and is stirred to be completely dissolved; step three, the deposited matter obtained in step two is cleaned, filtered, dried and crushed, and then the zinc selenite product is produced.

Description

technical field [0001] The invention relates to a production method of zinc selenite. technical background [0002] The molecular formula of zinc selenite is ZnSeO3, and its molecular weight is 192.35; it is an important chemical raw material, mainly used in the glass industry; zinc selenite is mainly used as a decolorizer, color complement agent and mold release agent for various types of glass. [0003] At present, the main production techniques of zinc selenite at home and abroad include zinc carbonate method and zinc chloride. [0004] The main disadvantages of the above two common production processes are: high production cost, relatively complicated equipment involved in the production process, small production capacity of a single set of equipment, and low utilization rate of raw material zinc. Contents of the invention [0005] The purpose of the present invention is to overcome the defect existing in the prior art, and provide a kind of high-efficiency, low-cost ...
