The optical properties of ALON (aluminum oxynitride) are presented. Op
tical scatter and index of refraction, and absorption of several diffe
rent compositions of ALON are compared. The temperature dependence of
emissivity of ALON was measured in the temperature range 46 degrees C
to 1200 degrees C. (C) 1998 Published by Elsevier Science B.V. All rig
