Problems solved by technology

There is also artificially synthesized mica in the prior art. Due to the inaccurate formula and the unreasonable production process, the operating conditions controlled in the preparation are not suitable, which makes the performance of the synthesized mica worse. There are impurities, and its crystal sheets are also small, which greatly reduce the comprehensive utilization value of synthetic mica
[0003] Traditional mica manufacturing equipment mostly uses DC two-phase power supply for power supply. Due to the low voltage of the two-phase power supply, the electrodes connected to the power supply have small arcing and generate less heat, resulting in low mica production and high cost; moreover, the flow through the electrodes The current is unstable, the power factor is low, and the impact on the power grid is large, which makes the traditional mica manufacturing equipment unsuitable for industrialized large-scale production

Description

technical field [0001] The invention provides an artificially synthesized crystal, in particular a preparation method for artificially synthesized mica. The invention also relates to a preparation device for the artificial crystal synthetic mica. Background technique [0002] Mica is a crystalline substance with good insulation, corrosion resistance and high temperature resistance, and is widely used in various fields. The natural mica commonly used in the prior art has some deficiencies, mainly in terms of corrosion resistance and high temperature resistance, which gradually cannot meet the higher requirements in use. In terms of high temperature resistance, natural muscovite melts at 400-500°C, and phlogopite also melts at 600-800°C. There is also artificially synthesized mica in the prior art. Due to the inaccurate formula and the unreasonable production process, the operating conditions controlled in the preparation are not suitable, which makes the performance of the ...
