Abstract
Disclosed herein are methods for producing glass articles by hot-melt processing techniques. The methods involve the use of arsenic-free chalcogenide glasses. Despite the absence of arsenic, the chalcogenide glasses have low characteristic temperatures and are stable against crystallization. The low characteristic temperatures render the glasses capable of being hot-melt processed using conventional equipment. The glasses disclosed herein are suitable for the fabrication of optical devices, including but not limited to IR-transmitting optical devices.
