Embodiment Construction

[0015] 1. Make a container; the container must be made of refractory bricks, and graphite electrodes are installed in the container, and the shape of the container will be made into an ellipse according to the square of the middle pole.

[0016] 2. The raw material formula and the particle size and purity of each material;

[0017] Quartz 33%-37%, 80-100 mesh 96-99%

[0018] Magnesium oxide 28%-31%, 80-100 mesh 94-98%

[0019] Alumina 9%-12%, 80-100 mesh 95-98%

[0020] Potassium fluorosilicate 18%-21%, 120-180 mesh 96-99%

[0021] Potassium carbonate 0.3%-0.4%, 20-40 mesh 94-98%.

[0022] 3. Preparation process:

[0023] (1) Process and mix the raw materials in the right 1 according to the required ratio, particle size and precision, and prepare them for later use.

[0024] (2) Prepare to make the container, because the following manufacturing process will generate high temperature, so the container must be made of refractory bricks, and graphite electrodes are installed...

Abstract

The present invention relates to artificial crystal synthetic mica and its preparation process. Its raw material composition includes (by wt%) 33%-37% of quartz, 28%-31% of magnesium oxide, 9%-12% of aluminium oxide, 18%-21% of potassium fluorosilicate and 0.3%-0.4% of potassium carbonate. Its preparation process includes the procedures of preparing raw materials, processing in container and melting, etc.

Description

technical field [0001] The invention relates to a method for preparing artificial crystal synthetic mica. Background technique [0002] Mica is a crystalline material with good insulation, corrosion resistance and high temperature resistance, and extremely low outgassing under high temperature and vacuum. It is widely used in military, civilian and various fields. But natural muscovite decomposes at 400-500°C, and the melting point of phlogopite is at 600-800°C. Its performance in all aspects, especially in high temperature resistance and corrosion resistance, can no longer meet the higher requirements of industry. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a highly efficient and energy-saving artificial crystal synthetic mica preparation process and device, and then produce artificial crystal synthetic mica and electrical appliances with better performance, higher purity and better fle...
