Processable microcrystalline glass ceramics is a synthetic mica as the main crystalline phase of fluorine gold mica microcrystalline glass, the main component is fluorine gold mica (Mg3K [AlF2O (SiO3) 3]) and silica as the main component of the glass composition. It is a new material in the seventies, with high mechanical strength, excellent dielectric properties and thermal properties, good chemical stability.

The most prominent feature of machinable ceramics is its good machinability. It can be turned, milled, planed, sawed, ground, cut, tapped, etc. using general-purpose metal processing equipment into a variety of parts with complex shapes, and can achieve a fairly high degree of machining accuracy. No special tools and equipment are required.

Machinable ceramics is a polycrystalline complex-phase material, a microcrystalline glass with synthetic mica microcrystals as the main crystal phase. The color is white and the organization is dense. The amount of microcrystals accounts for more than 50% of the total volume, microcrystalline particles between 5ν-20μ.

Machinable ceramic materials have excellent electrical insulation properties, high mechanical strength, and resistance to rapid cooling and heating (widely used in welding fixtures, optical glass molding dies, etc.). Its corrosion resistance is also superior to ordinary ceramics, its excellent corrosion resistance makes it used in various types of chemical equipment, relative to PTFE, it is more corrosion-resistant, not aging, long service life.

• Precision coil holders (high accuracy and dimensional stability);
• High-voltage insulators (with smooth surfaces and unaffected by arcing);
• Gaskets, cavities and reflectors in laser assemblies (precision surface treatment and heat resistance);
• Thermal fracture in high-temperature processing equipment;
• Coil support and vacuum feedthrough (vacuum stabilized and sealable);
• Aircraft hinges, retaining rings on windows and doors;
• Supports and components;
• Fixtures and reference blocks in power generation units.

Workable ceramics are susceptible to the effects of halogenated acids such as HCl (hydrochloric acid). Tests showed that a 2.52 gram (1 cc) sample of microcrystalline glass ceramic lost 100 mg (3.961 TP3T) in 24 hours when exposed to hydrochloric acid at a pH of 0.1. When exposed to sodium hydroxide at pH 13.2, it lost 0.3961 TP3T in 6 h. It undergoes fluoride precipitation above 600°C (in a vacuum) as boron trifluoride or hydrofluoric acid.
