摘　　要：本研究尝试将As_(2)Se_(3)红外硫系透镜生产过程中产生的块体玻璃废料进行回收利用,首先将清洗后的块体玻璃废料球磨成粉体,然后采用粉体热压技术实现高光学质量As_(2)Se_(3)玻璃片的制备。研究了粉体粒度、热压参数对制备的As_(2)Se_(3)玻璃光学性能的影响,对比了粉体热压法和熔融淬冷法制备的As_(2)Se_(3)玻璃的性能,评估了通过粉体热压途径制备红外硫系玻璃的可行性。结果表明:随着球磨时间的延长,As_(2)Se_(3)玻璃粉体的平均颗粒尺寸逐渐减小,且颗粒尺寸的分布趋于更加均匀;使用平均颗粒尺寸为9.7μm的粉体(球磨10 min),在压力为40 MPa、热压温度为250℃、热压时间为10 min的条件下获得的热压玻璃的致密度达到99.8%,其折射率与熔融淬冷法制备的玻璃的折射率接近(在10μm波长的折射率差仅为0.003),在10μm波长的透过率达61%(理论透过率为63.7%)。通过进一步提高玻璃粉体的纯度和尺寸均匀性,有望制备出与熔融淬冷法制备的玻璃性能相当的热压玻璃。This research attempts to recycle the bulk glass waste produced in the production of As_(2)Se_(3)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 As_(2)Se_(3)glass disks.The effects of powder size and hot pressing parameters on the optical properties of hot-pressed As_(2)Se_(3)glasses were studied,the properties of As_(2)Se_(3)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 As_(2)Se_(3)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 9.7μm(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 10μm),and its transmittance is as high as 61%at 10μm(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.
