Description
Technical Field

Background
Among natural micas, there are mainly muscovite and phlogopite which are used industrially in a large number, and since both of them contain OH-, they are called hydroxyl micas. Synthetic mica is often prepared using F-in place of OH-having a valence and radius similar to OH-, fluorophlogopite (KMg) 3 (Al-Si 3 O 10 )F 2 ) Large crystals are most easily formed and are therefore most widely used. The synthetic mica is referred to as fluorophlogopite. As can be seen from the components, the high temperature resistance of the mica can be greatly improved due to the use of F-instead of OH-. Tests prove that the fluorophlogopite is more resistant to high temperature (higher than 1200 ℃), has higher resistivity (higher 1000 times), is more resistant to acid and alkali, is transparent, can be peeled off separately and has high elasticity.
The main preparation principle of the synthetic mica is that the raw materials with proper proportion are mixed and then are melted at high temperature to obtain a melt, the melt is cooled, and when the temperature of the melt is lower than a freezing point, unordered accumulation of atoms (molecules) in the melt begins to become ordered arrangement and solid is separated out. The process therefore belongs to a solid-liquid phase transition process. The heating process, the container and the raw material proportion in the mica synthesis process all have influence on the state of solid precipitation, so that the quality of the product is directly influenced. For example, in the preparation of fluorophlogopite, an excessively fast cooling rate may result in the product being stevensite rather than mica, while a slower cooling rate may be advantageous for forming larger crystals.
