Problems solved by technology

[0004] There are several reference methods for the determination of vanadium content, but these methods cannot be directly applied to the determination of vanadium content in rare earth alloys. There are no national standard methods, industry standards and enterprise standard methods for the analysis and detection of vanadium content in rare earth alloys.

Embodiment Construction

[0019] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0020] The method steps of this specific embodiment are as figure 1 As shown, in the following specific embodiments, the reagents used are specifically:

[0021] Nitric acid: ρ1.42, superior grade; hydrochloric acid: ρ1.19, superior grade; hydrofluoric acid: ρ1.13, superior grade; perchloric acid: ρ1.68, superior grade; hydrochloric acid (1+1) , prepared in proportion with high-grade pure hydrochloric acid and high-purity water, and the experimental water is secondary pure water.

[0022] The specific operation steps are as follows: Weigh 0.1-0.2g rare earth alloy sample, accurate to 0.1mg, put it into a polytetrafluoroethylene beaker, add 10-15mL nitric acid, 5mL hydrofluoric acid, heat and dissolve on an electric heating plate at a low temperature of 100°C , add 5mL perchloric acid to fume until almost dry, remove and cool, add 10mL (1+1) hydrochloric acid...

Abstract

The invention discloses a method for measuring the content of vanadium in rare earth alloy, and belongs to the technical field of metallurgical analysis methods. The method aims at solving the problem that a suitable method for measuring the content of the vanadium in the rare earth alloy does not exist. The method includes the following steps of 1, preparing sample solutions; 2, preparing working standard curve solutions of the vanadium; 3, online measuring the content of the vanadium. The method is rapid is analysis speed, good in precision degree and high in accuracy degree, and the requirement of scientific research and the requirement of production can be completely met; the method is suitable for rapidly measuring the content of the vanadium in the rare earth alloy.

Description

technical field [0001] The invention specifically relates to a method for measuring vanadium content in rare earth alloys, and belongs to the technical field of metallurgical analysis methods. Background technique [0002] Rare earth is known as the "gold" of industry. Due to its excellent optical, electromagnetic and other physical properties, it can be combined with other materials to form a variety of new materials with different properties. Its most notable function is to greatly improve the quality and performance of other products. . For example, the tactical performance of steel, aluminum alloy, magnesium alloy, and titanium alloy used to manufacture tanks, aircraft, and missiles has been greatly improved. Moreover, rare earths are also lubricants for many high-tech industries such as electronics, lasers, nuclear industry, and superconductivity. Rare earth alloys mainly include: tungsten rare earth alloy, rare earth aluminum alloy, rare earth ferrosilicon and so on....
