Embodiment Construction

[0022] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] The present invention is a kind of preparation method of synthetic electronic mica, and its preparation method comprises the following steps:

[0024] In the first step, the furnace body made of corundum casting is selected as the calciner, and graphite electrodes are installed in the furnace body, and the inner surface of the furnace body is coated with an anti-stick coating;

[0025] In the second step, five kinds of synthetic mica raw materials: calcined talc, heavy magnesium oxide, potassium fluorosilicate, aluminum oxide, and potassium carbonate are added to the calciner. Layer of high-quality mica sheet;

[0026] The third step is to heat and calcine the raw mate...

Abstract

The invention discloses a method for producing electronic mica via artificial synthesis. The method includes the steps of selecting a furnace poured from corundum as a calcining furnace, arranging a graphite electrode in the furnace, and coating an anti-sticking coating layer on the inner surface of the furnace; adding five raw materials including calcined talcum, heavy magnesium oxide, potassium fluosilicate, aluminum oxide and potassium carbonate for the mica into the calcining furnace, and simultaneously paving a flat layer of high-quality mica plates on the middle layer of the furnace; heating to calcine the raw materials at the furnace temperature ranging from 1600 DEG C to 1800 DEG C, calcining with constant temperature firstly and then calcining with reducing-temperature secondarily; and finally naturally cooling the raw materials in the furnace. The method for producing the electronic mica is simple in process, high in production efficiency, low in cost and labor-saving, the prepared product is high in quality and grade, and automatic production of the electronic mica is realized. Besides, the electronic mica produced can be widely utilized in the fields such as electronic industry, military industry and aviation industry, can bring good economic benefits and social benefits, and has broad marketing prospect.

Description

technical field [0001] The invention relates to a preparation method of artificially synthesized mica, in particular to a preparation method of artificially synthesized electronic mica. Background technique [0002] Mica is a general term for a class of layered silicate minerals. Natural mica mainly includes muscovite KAl 2 (AlSi 3 o 10 )(OH) 2 and Phlogopite KMg 3 (AlSi 3 o 10 )(OH) 2 , they all contain structural water, so the use temperature is not high, the former is about 550 ° C, and the latter is 880 ° C. Synthetic mica does not contain structural water. Use F in synthetic mica - Ions replace (OH) in natural mica - Ions, so the long-term use temperature of synthetic mica can reach 1100 ℃. In the prior art, synthetic mica is a high-temperature-resistant insulating material made of five chemical raw materials such as potassium fluorosilicate, quartz powder, fused magnesia, alumina and potassium carbonate through high-temperature melting. Synthetic mica made ...
