Effects of composition and heat treatment on the microstructures of mica vitrocrystalline materials
During the last decade a new mica glass-ceramic based on fluorphlogopite has been made, which is readily worked, mechanically strong, and chemically stable. (Items of this material are readily worked with steel tools on ordinary metal-working machines, and they have high mechanical strength and good shock and thermal resistance as well as elevated values for the electrical parameters.) This paper considers the microstructures of mica vitrocrystalline materials in relation to the heat-treatment conditions for glasses of various compositions. It is concluded that it is desirable to use two-stage crystallization to produce glass-ceramics based on fluorphlogopite with a given structure; and the roles of the primary and secondary stages of heat treatment in producing the optimum structure are established for mica-bearing glass-ceramics of various compositions.
