Infrared transmitting glass ceramics a review.

Cunming liu gao tang lan luo wei chen phase separation inducing controlled crystallization of gese2 ga2se3 csi glasses for fabricating infrared transmitting glass ceramics journal of the american ceramic society 10 1111 j 1551 2916 2008 02832 x 92 1 245 248 2008. Glasses as well as glass based ceramics offer the advantage of unique rheological properties. First when heated above t g this glass has to precipitate nanosize particles and avoids a fast growth of each individual nano crystal. 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.

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. The demand for infrared materials which exhibit higher performance is still growing. Depending on the wavelengths being used a number of glass materials can be considered. Transmission of infrared ir wavelengths is an important property for applications such as vision systems spectroscopy and defense related uses.

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. A review infrared transmitting glass ceramics. 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 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.

Applications for infrared ir transmitting glass ceramics have included far infrared fibers 21 scintillators 22 24 nonlinear optical devices 25 26 and bulk optics. 27 28 table 1. 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.
