| 摘 要： | 以纯度大于99.9%(质量分数)的高纯ZrO2和SiO2为原料,少量TiO2为添加剂,采用高温固相法合成高纯锆英石(ZrSiO4)粉料。研究温度和反应时间对高纯锆英石合成效率的影响,发现粒度小于50 μm的原料粉末经1 500 ℃反应48 h后,ZrSiO4相的含量可以达到95.77%(质量分数)。将合成的高纯锆英石粉料球磨并冷等静压成型后,在1 550 ℃高温烧结成高纯致密锆英石砖。高纯致密锆英石中杂质Fe的含量仅为29 μg/g,Cu的含量小于1 μg/g,是普通商用致密锆英石的1/10;对磷酸盐玻璃静态光吸收损耗的影响仅为普通致密锆英石材料的1/3。将这种高纯致密锆英石材料用于激光玻璃窑炉,有助于降低玻璃对1 053 nm激光的损耗,提升激光玻璃的激光性能。

| Abstract: | High-purity zircon (ZrSiO4) powders were synthesized by high-temperature solid-phase reaction method, using 99.9% (mass fraction) high purity ZrO2 and SiO2 powders as raw materials and small amount of TiO2 as additive. The effects of temperature and reaction time on the synthesis efficiency of high-purity zircon powders were studied. It is found that the fraction of the ZrSiO4 phase reaches 95.77% (mass fraction) after the solid-phase reaction is carried out at 1 500 ℃ for 48 h using raw material powders with particle size less than 50 μm. The prepared high-purity zircon powders were used as a raw material, and sintered at a high temperature above 1 550 ℃ after ball milling cold isostatic pressing to form a high-purity dense zircon brick. The concentrations of Fe and Cu impurities in high-purity dense zircon are 29 μg/g and less than 1 μg/g, respectively, which are only 1/10 of those in the commercial high dense zircon samples. The static optical loss of phosphate glass caused by the high-purity dense zircon samples is only 1/3 of that of the commercial high dense zircon samples. Using this high-purity dense zircon material for laser glass furnaces can reduce the optical loss at 1 053 nm and improve the laser performance of laser glasses. |
