Preparation method of platinum sheet target material

[0024] A method for preparing a platinum sheet target according to an embodiment of the present invention, the method comprising the steps of:

[0025] (1) After the platinum ingot was held at 1100 ° C for 1 hour, the first rolling was carried out to obtain a thickness of 3 mm platinum sheet; the first rolling included several recycled rolling A, the rolling path of the circulation rolling A was 10 The quarter; each of the rolled rolling A is 2.5 mm; each of the completion of a circulating rolling A is completed to 1100 ° C;

[0026] (2) The platinum sheet processed after step (1) is annealing, and the annealing treatment is to sinter the platinum sheet after the step (1) by the natural gas spray gun into a red cooling;

[0027] (3) The platinum sheet after treatment with step (2) is a platinum sheet having a thickness of 0.08 mm; the amount of rolling amount of each of the second rolled rolled is 0.20 mm;

[0028] The rolling direction of the plurality of circulation rolling A is th
