ZnSe powders have been synthesized using two different methods: hydrothermal and high energy ball milling. The obtained powders have been dispersed and separated through the ultrasonic process. A comparison has been made between the powders by means of X-Ray powder Diffraction (XRD) and Scanning Electron Microscopy (SEM). The as-prepared ZnSe powders and the fine powders obtained after ultrasonic separation have been sintered by conventional uniaxial Hot-Pressing (HP) technique in order to prepare ZnSe bulk ceramics. The optical properties of the ceramics have been characterized and compared. As a result, the sintering of the fine hydrothermal powder presents the best transparency in the visible and infrared range. The transmission exceeds 60% in the range from 11 to 19 μm..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
