Nanometer ball with strontium fluoride and production thereof

Abstract

A strontium fluoride ball and its production are disclosed. The procedure includes preparing ammonium fluoride solution with concentration 5.0-38g / L, preparing strontium nitrate solution with concentration 4.5-105g / L, adding ammonium fluoride solution into strontium nitrate solution in proportion=2:1, precipitating out deposits with ultrasonic 6-30mins, centrifugal separating out deposits, washing by water and alcohol, and vacuum drying at room temperature to obtain white powdery SrF2 nanometer ball.

Description

1. Technical Field

[0001] The present invention relates to strontium fluoride SrF 2 Submicron and micron ball and its preparation method. Specifically, it is SrF with a spherical structure 2 SrF prepared by sonochemical method 2 Sub-micron and micron spheres. 2. Background technology

[0002] Since Gleiter et al. [see: Birringer R, Gleiter H et al. PhysLett.1984, A(8):365-369.] first prepared nano-bulk materials, the preparation and physical and chemical properties of nano-materials have become the current international frontier Research one.

[0003] Traditional methods for preparing nanomaterials can be generally divided into three categories: gas phase method, liquid phase method and mechanical pulverization method. The vapor phase method mainly includes vapor phase condensation method, sputtering method, hybrid plasma method, laser induced chemical vapor deposition (LICVD) and chemical vapor deposition (CVD). Liquid-phase methods include chemical deposition, hydrothermal, mic...
