Infrared transmitting glass ceramics a review.

We have studied the mechanical properties of a new family of infrared transmitting glass ceramics based on the ges 2 sb 2 s 3 cscl system. Cs based crystals have been generated inside the glass matrix and the crystal size is controlled to be less than 100 nm in order to keep the transparency of the composite materials. Glasses as well as glass based ceramics offer the advantage of unique rheological properties. The demand for infrared materials which exhibit higher performance is still growing.

A large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications. A review mccloy john s. The key factor for controlling the glass to crystal transformation in an infrared transmitting glass ceramic is in the selection of a suitable glass composition which must have the two following specificities. A large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications.

First when heated above t g this glass has to precipitate nanosize particles and avoids a fast growth of each individual nano crystal. Some examples of infrared transmitting glasses. Qiao amy 2013 06 04 00 00 00 a large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications. Transmission of infrared ir wavelengths is an important property for applications such as vision systems spectroscopy and defense related uses.

Known optical and physical property data was summarized for many ternary sulfides as well as their constituent binary sulfides. 27 28 table 1. Depending on the wavelengths being used a number of glass materials can be considered.
