Abstract

The invention provides a method for measuring silicon elements in a Fe-based amorphous alloy. A sample in dissolved in a hydrochloric acid and nitric acid mixed acid, perchloric acid smokes, silicic acid of colloid is dehydrated, and insoluble silicic acid is formed; a precipitate is ignited to be constant; sulfuric acid and hydrofluoric acid are added for treatment, so that silicon escapes in the form of silicon tetrafluoride and then is ignited to be constant; the mass fraction of silicon is calculated according to the mass difference before and after hydrofluoric acid treatment. As the Fe-based amorphous alloy is a relatively special Fe-based alloy, the silicon content has no standard at present. The method fills up the technical blank, the detection method is accurate, high in precision and wide in detection range, and the silicon content of the Fe-based amorphous alloy can be 15% or above.

Description

technical field [0001] The invention relates to the technical field of metallurgical analysis, in particular to a method for measuring silicon in iron-based amorphous alloys. Background technique [0002] The iron-based amorphous alloy is composed of 80% Fe and 20% Si and B-type metal elements. It has high saturation magnetic induction, magnetic permeability, excitation current and iron loss, etc., which are superior to silicon steel sheets. Especially It has low iron loss (1 / 3-1 / 5 of oriented silicon steel sheet), and it can save energy by 60-70% instead of silicon steel as distribution transformer. , because it conforms to the current environmental needs of energy conservation and emission reduction, amorphous alloy transformers are the future development direction. Large-scale promotion of amorphous alloy transformers has become the consensus of all parties in the industry and market. Therefore, the determination of silicon, which is the main element in amorphous alloys...
