Abstract

The invention discloses a purification auxiliary material of microcrystalline graphite and a production method thereof. The purification auxiliary material of microcrystalline graphite is composed of the following materials in percentage by weight: 40-50% of microcrystalline graphite, 15-25% of hydrochloric acid, 12-18% of phosphoric acid and 15-30% of ammonium fluoride. The production method of the purification auxiliary material of microcrystalline graphite comprises the following steps: (1) selecting microcrystalline graphite, hydrochloric acid, phosphoric acid and ammonium fluoride according to the percentage by weight; (2) sequentially mixing microcrystalline graphite with hydrochloric acid, phosphoric acid and ammonium fluoride; and (3) placing the uniformly-mixed mixture in an environment at a temperature of 60-100 DEG C, drying the mixture, and cooling to a room temperature, thereby obtaining the purification auxiliary material of microcrystalline graphite. The purification auxiliary material of microcrystalline graphite and the production method thereof disclosed by the invention are simple in formula, achieve the requirement of high purity, and are wide in application range.

Description

technical field [0001] The invention relates to a purification auxiliary material, in particular to a microcrystalline graphite purification auxiliary material and a preparation method thereof. Background technique [0002] Graphite is one of the most important simple substances of carbon, which is formed at high temperature. It is abundant in nature and widely distributed in mineral deposits. Graphite has a typical layered structure, carbon atoms are arranged in layers, each carbon is connected to three adjacent carbons at equal distances, and the carbons in each layer are arranged in a six-point ring. The carbon-carbon distance between the layers is 0.142nm, and the interlayer carbon-carbon distance is 0.340nm. The carbons in the layers are connected by covalent bonds, which also have the properties of some metal bonds, and the interlayers are molecular bonds. This difference in chemical bonds leads to graphite The physical properties have obvious anisotropy and conductiv...
