Embodiment 1
[0045] Step 1 Sponge zirconium hydropermeation:
[0046] The material of the grinding balls used in this embodiment is cemented carbide balls.
[0047]Take 2kg of sponge zirconium whose composition requirements meet the industry standard of YS / T397~2007, and mechanically crush it to a particle size of less than 3mm, and place it in a vacuum furnace. The stages are kept warm for 1 hour each, and at the end of the heat preservation, high-purity hydrogen gas permeates for 2 hours at a constant temperature of 650°C;
[0048] Step 2 mechanically crushing zirconium hydride particles:
[0049] Divide the zirconium hydride particles obtained in the first step into 4 groups of 500g each, numbered 1#, 2#, 3#, 4#, and add 50g sodium chloride, 50g potassium chloride, 62.5g sodium sulfate, 62.5 g Potassium sulfate is subjected to high-energy ball milling in anhydrous ethanol medium, the grinding balls are cemented carbide balls, the mass ratio of grinding balls to zirconium hydride is 8:...
Embodiment 2
[0060] The material of the grinding balls used in this embodiment is cemented carbide balls.
[0061] Step 1 Sponge zirconium hydropermeation:
[0062] Take 2kg of sponge zirconium whose composition requirements meet the industry standard of YS / T397~2007, and mechanically crush it to a particle size of less than 3mm, and place it in a vacuum furnace. The stages are kept warm for 1 hour each, and at the end of the heat preservation, high-purity hydrogen gas permeates for 2 hours at a constant temperature of 650°C;
[0063] Step 2 mechanically crushing zirconium hydride particles:
[0064] Add 200g of sodium chloride to the zirconium hydride particles obtained in the first step and carry out high-energy ball milling in anhydrous ethanol medium. The mass ratio of balls to zirconium hydride is 8:1, the ball milling speed is 40r / min, and the liquid level of the ball milling medium is high Take 2 cm of zirconium hydride powder, and after ball milling for 2 hours, vacuum-dry at a v...
