The invention provides a method for detecting the grade of diamond micro-powder by utilizing Raman spectroscopy and application of the method in detection of the grade of the diamond micro-powder. Themethod comprises the following steps: detecting a fluorescence intensity value and a Raman spectrum intensity value of a diamond micro-powder sample; and calculating according to a formula to obtainthe grade of the diamond micro-powder. According to the method, the grade of the diamond micro-powder can be accurately detected, the quality of the diamond micro-powder is controlled, and the methodis particularly helpful to the use effect of the diamond micro-powder. The method is convenient and fast, and has a good application effect.
Description
technical field [0001] The invention belongs to the technical field of superhard material detection, and in particular relates to a method for detecting the grade of diamond micropowder by using Raman spectrum and its application in detecting the grade of diamond micropowder. Background technique [0002] Diamond micropowder has high hardness and good wear resistance, and is widely used in cutting, grinding, drilling, polishing, etc. With the development and progress of science and technology, the market demand for diamond micropowder is increasing, and the quality requirements are also getting higher and higher. For diamond micropowder, factors affecting the quality include particle strength (grade), particle size composition, particle shape, impurity content and other factors. For the particle size composition, particle shape, impurity content and other items of the micropowder, there are relatively mature inspection methods, but there is no way to inspect the particle st...
