preparation example Construction

[0021] The preparation method of the iron tailings glass-ceramics film provided by the embodiment of the present invention comprises the following steps: using the iron tailings glass-ceramics as the sputtering target material, and coating the iron tailings glass-ceramics on the metal substrate by magnetron sputtering coating surface. The preparation of iron tailings glass-ceramic thin films by magnetron sputtering has the advantages of low coating temperature, fast deposition rate, high efficiency, easy process control and large coating area.

[0022] Optionally, the metal substrate may be, for example, an aluminum sheet, or a metal substance such as carbon steel that has a different dielectric property from the coating. Preferably, the thickness of the substrate may be, for example, 1.5-2.5 mm, and this thickness range is more favorable for the deposition of target atoms or molecules on the substrate to form a thin film.

[0023] Preferably, before the metal base is put int...

Abstract

The invention relates to an iron tailings glass-ceramic film and a preparation method and application thereof, belonging to the field of materials. The preparation method comprises the steps of using iron tailing glass ceramics as a sputtering target, and magnetron sputtering coating to coat the iron tailing glass ceramics on the surface of a metal substrate. The method is simple and efficient, and the tailings are used instead of pure reagent raw materials, thereby reducing production costs. The iron tailings glass-ceramic thin film is prepared by the above preparation method, and has good thickness and binding force and high resistivity. Using the iron tailings glass-ceramic film as an insulating film material can not only avoid the tailings from causing harm to the environment, but also reutilize the tailings resources and effectively increase the added value of the tailings.

Description

technical field [0001] The invention relates to the field of materials, and in particular to an iron tailings glass-ceramic film and its preparation method and application. Background technique [0002] The main hazard of iron tailings is that it not only needs to occupy a large amount of land resources, but also brings huge pollution hazards to the environment. The chemical composition of tailings is very complex and contains a large amount of elements. During the process of open-air accumulation of tailings, After being eroded, some of the chemical elements migrate chemically, causing serious damage to the local living environment. The particle size of iron tailings is very small, and the dust generated by tailings ponds can fly far away. The dust weather in cities where most iron and steel enterprises are located in my country is very serious. [0003] Due to the continuous development of my country's iron and steel industry, the number of iron tailings is increasing. Th...
