This research attempts to recycle the bulk glass waste produced in the production of As2Se3 infrared chalcogenide lenses. First, the cleaned bulk glass waste was ground into powder, and then the powder hot pressing technique was used to achieve the high optical quality As2Se3 glass disks. The effects of powder size and hot pressing parameters on the optical properties of hotpressed As2Se3 glasses were studied, the properties of As2Se3 glasses prepared by powder hot pressing method and melt quenching method were compared, and the feasibility of preparing infrared chalcogenide glass by powder hot pressing technique was evaluated. The experimental results show that the mean particle size of As2Se3 glass powder decreases gradually with the prolongation of milling time, and the distribution of particle size tends to be more uniform. Using the powder with mean particle size of 9.7 μm (the milling time is 10 min), a glass disk with compactness of 99.8% is obtained under the conditions of pressure of 40 MPa, hot pressing temperature of 250 ℃ and holding time of 10 min. The refractive index of the hotpressed glass is close to that of the glass prepared by melt quenching method (the difference is only 0.003 at 10 μm), and its transmittance is as high as 61% at 10 μm (the theoretical transmittance is 63.7%). By further improving the purity and size uniformity of glass powder, it is expected to prepare hotpressed glass with the same performance as the glass prepared by melt quenching method.
