Abstract
A solid vitreous composition has the formula: Te.sub.100-x-z X.sub.x Z.sub.z wherein x represents chlorine, bromine or iodine, Z represents sulfur and/or selenium; x represents the molar percentage of X and ranges from 5 to 67; z represents the molar percentage of Z and ranged from 0 to 60; it being understood that the sum (x+z) ranges from 33 to 85. A method for the preparation of this composition is disclosed as is its use in the field of optoelectronics and infra-red transmission.
