Method for utilizing ion implantation technology to modify serpentine

Abstract

The invention relates to a method for utilizing ion implantation technology to modify serpentine, which belongs to the technical field of physical technology material modification. The method is characterized in that serpentine powder is placed in an ion implantation machine, a cavity of the ion implantation machine is vacuumized, and the vacuum degree requirement is 1*10-3-1*10-6Torr. NH3 is injected in ion mode, ion implantation energy is 30-60kev, implantation flux is 1*1017cm-2, and the implantation time is 3 to 20min. Finally samples where ion is implanted are taken out to obtain serpentine samples with N element implantation.

Description

technical field

[0001] The invention relates to a method for modifying serpentine by ion implantation technology, and belongs to the technical field of physical technology material modification. Background technique

[0002] my country is one of the big countries with serpentine resources, serpentine (Mg 3 [Si 2 o 3 ](OH) 4 or 3MgO·2SiO 2 2H 2 O) The resources are very rich, and the amount of mineral deposits is huge. The proven reserves in Anhui Province alone are more than 1 billion tons. my country's serpentine resources are widely distributed, with the largest reserves in Anhui, Jiangxi, Sichuan, and Henan, followed by Shandong, Jiangsu, Shaanxi, and Inner Mongolia. Because serpentine ore has leaf-like or phosphorus flaky crystals and large differentiation layers, it is open-pit mining in my country, and a large amount of crushed ore is produced during the mining process, with a particle size of <2-3cm, which is generally called serpentine powder or tailings. ...
