Anti-oxidation device and method for calcining and preparing new material

Abstract

The invention discloses an anti-oxidation device and method for calcining and preparing a new material, and belongs to the field of metallurgical chemical engineering equipment. The anti-oxidation device comprises a small crucible (6) with a small crucible cover (5) and a big crucible (1), wherein a to-be-calcined material (7) is held in the small crucible (6); the small crucible (6) is arranged inside the big crucible (1); the lower part of the big crucible (1) is filled with high temperature oxytropic powder (4) capable of completely embedding the small crucible (6); the upper part of the big crucible (1) is filled with a sealing layer used for sealing the big crucible (1). Through the simple and effective combination of the inner system and the outer system, the device not only prevents material oxidation, but also ensures normal conducting of the calcination chemical reaction, is convenient to operate, time-saving, safe and low in cost, and is extremely suitable for common teaching and experiment, as well as small and medium size industrial manufacture users who use the device infrequently or discontinuously.

Description

technical field [0001] The invention belongs to the field of metallurgical and chemical equipment, and relates to an anti-oxidation device and method for preparing new materials by calcination. Background technique [0002] When preparing new materials by calcination of metal materials, inorganic non-metal materials, organic materials, or composite materials of the above materials, it is often necessary to provide an oxygen-free environment to prevent the oxidation of the material without hindering the normal progress of the calcination chemical reaction. The existing technology is often carried out in a vacuum heat treatment furnace, but the operation of the vacuum heat treatment furnace is cumbersome, and the equipment cost and maintenance are very expensive, so it is only suitable for fine experimental research or industrial professional production; and for teaching and experiments that do not require high precision , It is not necessary for small and medium-sized industr...
