Infrared Transmitting Glass Ceramics A Review

Both on the thermal and mechanical side as well as on the width of the optical window with an extension of the transparency towards the long wavelength region to satisfy the requirements of space applications.

Infrared transmitting glass ceramics a review.

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. 27 28 table 1. First when heated above t g this glass has to precipitate nanosize particles and avoids a fast growth of each individual nano crystal. Transmission of infrared ir wavelengths is an important property for applications such as vision systems spectroscopy and defense related uses.

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 infrared transmitting glass ceramics. The demand for infrared materials which exhibit higher performance is still growing. 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.

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. 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. 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. Known optical and physical property data was summarized for many ternary sulfides as well as their constituent binary sulfides.

A review mccloy john s. Applications for infrared ir transmitting glass ceramics have included far infrared fibers 21 scintillators 22 24 nonlinear optical devices 25 26 and bulk optics. Glasses as well as glass based ceramics offer the advantage of unique rheological properties.
