Description

technical field

[0001] The invention belongs to the technical field of chemical detection methods, and in particular relates to a specific method for measuring impurity elements in zirconium diboride by inductively coupled plasma emission spectrometry. Background technique

[0002] At present, there are few research reports on the chemical composition analysis of zirconium diboride. The determination methods of components and impurity elements in zirconium diboride in the literature are all determined by chemical methods, and the method of measuring by instruments has not been reported.

[0003] The main components of zirconium diboride are 20% boron and 80% zirconium, and other chemical components are Al, Mg, Fe, Cu, Ni, Cr, Mo, Co, Mn, Ti, Th, Ca, Pb, Bi , Cd, Si, Zn, V, Hf, In, Sn, W, Sm, Eu, Gd, Dy 26 kinds, it is necessary to develop an inductively coupled plasma emission spectroscopic analysis technology for zirconium diboride in zirconium And the determination metho...

Examples

Embodiment Construction

[0033] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0034] A method for measuring impurity elements in zirconium diboride of the present invention comprises the following steps:

[0035] (1) Weigh zirconium diboride sample

[0036] Weigh a zirconium diboride sample with a mass of 0.125g, accurate to 0.0001g;

[0037] (2) Determination of sample concentration

[0038] Determine that the sample concentration of boron in the sample solution that needs to be controlled during the determination of the sample is 1000 μg / mL;

[0039] (3) Dissolve the zirconium diboride sample in acid

[0040] According to the chemical composition of zirconium diboride samples, zirconium diboride theoretically consists of 20% boron and 80% zirconium. As a coating material, a small amount of carbon is added to improve the oxidation resistance of zirconium diboride. Therefore, carbon cannot be dissolved and suspended ...
