Abstract

The invention relates to the technical field of magnesium diboride, and discloses new material research magnesium diboride high-purity extraction equipment. The equipment comprises a vacuum box, a mercury box is fixedly connected to the left side of the vacuum box, a heat conduction rod is arranged on the right side of the mercury box in a penetrating mode, a mercury plate is slidably connected tothe interior of the mercury box, an extrusion rod is fixedly connected to the top of the mercury plate, an exhaust pipe is fixedly connected to the top of the vacuum box, a ventilation wheel is rotatably connected to the interior of the exhaust pipe, a limiting plate is connected to the side face of the limiting rod in a meshed mode, a guide pipe is connected to the side face of the extrusion plate in a meshed mode, and a magnesium powder box is fixedly connected to the left side of the guide pipe. According to the new material research magnesium diboride high-purity extraction equipment, through cooperative use of the mercury box and the exhaust pipe, the effects of preventing the gas formed by volatilization of magnesium powder from influencing the reaction of the magnesium powder and boron powder and preventing magnesium tetraboride from appearing in a product during preparation of magnesium diboride are achieved.

Description

technical field [0001] The invention relates to the technical field of magnesium diboride superconductors, in particular to a high-purity extraction device for new material research magnesium diboride. Background technique [0002] A superconductor, as the name implies, is a conductor that has no energy dissipation after passing a current. In 1911, Dutch scientists discovered the superconductivity of mercury. In early March 2001, Japanese scientists reported that the binary material magnesium diboride (MgB2) was around 39K. exhibit superconducting properties. [0003] When preparing superconductors by magnesium diboride, magnesium diboride with extremely high purity is required, so it is necessary to prepare high-purity magnesium diboride. The existing preparation method is to mix pure coal powder and boron powder in a vacuum environment according to a certain ratio Mixing and heating, and filling with appropriate nitrogen gas during this process, however, because magnesium...
