Abstract

The invention provides a CuAl alloy sample preparation method suitable for ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer), which comprises the following steps: mixing a CuAl alloy target material and mixed acid, and preserving heat for 8-10 minutes to obtain a sample solution; wherein the mixed acid is composed of nitric acid and hydrofluoric acid in a volume ratio of 1:(1.8-2.2), the concentration of the nitric acid is 65-68wt%, and the concentration of the hydrofluoric acid is 35-38wt%. According to the CuAl alloy sample preparation method, the CuAl alloy target material can be completely dissolved within 10 min, the dissolution efficiency is high, ICP-OES testing is not affected after dissolution, and the blank of sample preparation during ICP-OES testing of the CuAl alloy target material is filled.

Description

technical field [0001] The invention belongs to the technical field of semiconductors and relates to a method for analyzing CuAl alloys, in particular to a CuAl alloy sample preparation method suitable for ICP-OES. Background technique [0002] Magnetron sputtering technology is widely used in various fields such as material surface device, material surface modification and optical device production. The principle of magnetron sputtering is: in a vacuum state, when a negative potential is applied to the magnetron sputtering target and a positive potential is applied to the workpiece to be coated, an electric field is formed in the vacuum chamber where the magnetron sputtering target is located, and then The process carrier gas is filled into the vacuum chamber. Under a certain pressure and temperature, a discharge phenomenon will occur between the positive potential and the negative potential. The electrons move along the circular orbit and hit the process carrier gas molecu...
