Advancement in hermetic (vacuum-tight) edge-sealing materials has been one of the challenges since decades because of the existing cost, use of hazardous substance and complexity-to-construct issues in vacuum glazing. This paper presents novel experimental findings with designs and methods developed to construct and analyse thermal performance of the fusion edge-sealed vacuum glazing. The novel concept of fusion edge-seal consists of forming a thin glass-metallic rigid textured layer, in which the formation processes and experimental glass-metallic textured surface bonding property tests of 15 samples are microstructurally analysed using FIB-SEM and optical microscopy and succeeded the correct mixture of B₂O₃38-Sn62 wt%. Experimental analyses of at least 60 samples conducted using different techniques and Pb-free materials, among which five vacuum glazing samples of various designs and techniques discussed in this paper. The fusion edge-sealed vacuum glazing, constructed with bonded Sn62-B₂O₃38 wt% surface textured fused with Sn90-In10 wt% alloy at 450˚C, achieved at the hot-plate surface heat induction of 50±5˚C and the cavity vacuum pressure of 8.2·10^-4 Pa. Validated 3D FEM employed and the centre-of-sheet and total thermal transmittance values of fusion edge-sealed vacuum glazing (sample ‘A5’), area of 300·300mm with 10 mm wide fusion edge-seal, predicted to be 1.039 and 1.4038 Wm^-2K^-1, respectively.

数十年来，由于真空玻璃的现有成本，有害物质的使用以及构造的复杂性，密封（真空密封）边缘密封材料的发展一直是挑战之一。本文介绍了新颖的实验发现，并设计和开发了用于构造和分析融合边缘密封真空玻璃的热性能的方法。融合边缘密封的新概念包括形成薄的玻璃-金属刚性织构层，其中使用FIB-SEM和光学显微镜对15个样品的形成过程和玻璃-金属织构化表面粘合性能测试进行了微观结构分析，并成功完成了B ₂ O ₃的正确混合物38-Sn62重量％。使用不同的技术和无铅材料对至少60个样品进行了实验分析，其中有5个本文讨论的各种设计和技术的真空玻璃样品。融合边缘密封的真空玻璃窗，在450˚C的温度下，通过粘合Sn62-B ₂ O ₃ 38 wt％的表面纹理与Sn90-In10 wt％的合金融合在450˚C的温度下构成腔真空压力为8.2·10 ^-4 Pa。采用验证的3D FEM以及融合边缘密封真空玻璃（样本“ A5”）的薄片中心和总热透射率值，面积为300·300mm，10毫米的融合边缘密封，预计分别为1.039和1.4038 Wm ^-2 K ^-1。
