Problems solved by technology

[0002] The existing zirconium hydride is mainly prepared by directly hydrogenating zirconium metal powder at high temperature. Due to the difficulty in obtaining these metal powders, the price is expensive. The production of zirconium hydride by the existing production method consumes a lot of energy and is relatively expensive. High, not suitable for industrial mass production, thus limiting the application of zirconium hydride

Embodiment Construction

[0008] Below in conjunction with specific embodiment the present invention is described in further detail:

[0009] 16 examples of the preparation method of zirconium hydride:

[0010] 1. Determine the type and amount of zirconium raw materials according to the convenience of raw materials and equipment conditions.

[0011] 2. Select additives. According to the selection of different additives, the conversion weight A of calcium and lithium in the hydrogenation reaction is more than 5% of the sum of the zirconium weights. B is the weight sum of calcium in the hydrogenation reaction material, and C is the weight sum of lithium in the hydrogenation reaction material.

[0012] 3. The amount of metal magnesium is determined by converting the oxygen in the reaction material into magnesium oxide and the excess is 10%.

[0013] 4. The selected zirconium raw material (in the embodiment without additive) or the selected zirconium raw material and the additive (in the embodiment with ...

Abstract

The invention discloses a method for preparing zirconium hydride, and relates to the technology field of metal smelting. The method includes mixing zirconium material containing zirconia, calcium zirconate or lithium zirconate with the magnesium metal under a calcium or lithium-contained condition; placing into a sealed container, introducing hydrogen and heating to carry out the hydrogenation toconvert the zirconium in the reaction material into the zirconium hydride; and removing impurities by using acid to obtain the zirconium hydride. Compared with the prior art, the method has the advantages of greatly reduced comprehensive energy consumption, and process cost reduced by more than 20%, and is applicable for industrial production.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a method for preparing zirconium hydride. technical background [0002] The existing zirconium hydride is mainly prepared by directly hydrogenating zirconium metal powder at high temperature. Due to the difficulty in obtaining these metal powders, the price is expensive. The production of zirconium hydride by the existing production method consumes a lot of energy and is relatively expensive. High, not suitable for industrial mass production, thus limiting the application of zirconium hydride. Contents of the invention [0003] The problem to be solved by the present invention is to provide a method for preparing zirconium hydride with low process cost and suitable for industrial application. [0004] The preparation method of zirconium hydride of the present invention comprises the following steps: mixing zirconium raw material with magnesium metal under the condition ...
