“…Metal has excellent plasticity, electrical conductivity and thermal conductivity. Devices consisting of glass and metal are widely applied to many fields including semiconductor devices, automotive manufacturing, medical equipment, micro electro mechanical system, etc [1][2][3][4]. With the miniaturisation and the expansion of application fields of these devices, micro-joining between glass and metal is becoming one of the indispensable techniques for assembling and hermetic sealing of micro-components [5][6][7].…”

Devices consisting of glass and metal are widely applied to many fields. With the miniaturisation and the expansion of application fields of these devices, the requirement of micro-joining between glass and metal is becoming higher. In this work, silica glass and 304 stainless steel were welded by the infrared nanosecond fibre laser. The welding quality was optimised by varying the laser parameters. The joint strength reached 16.39 MPa. The mechanism of the welding between the two materials was investigated. The results demonstrated the elemental diffusion in the interface between silica glass and 304 stainless steel under laser heating, where Fe, Cr and Si were the crucial factors in forming the welds. During the elemental diffusion, Cr was much easier to diffuse into glass than Fe. In the interface, Fe-O-Si bonds were observed. Moreover, increasing Cr content in the interface is a probable approach to improve the joint strength.

“…In total, 55% of receiver failure arises due to broken glass envelopes and 29% due to loss of vacuum arising due to failure of glass to metal seal. [ 8 ] Intensive research has been carried out to find out the reason for the high failure rate in evacuated assembly, [ 7,11 ] but the problem persists without much improvement. To overcome the issue of vacuum fracture, non‐evacuated cavity receivers have been developed with comparable thermal performance to evacuated receivers.…”

Solar thermal technology promises to be a significant component of the future renewable energy mix. As the most mature solar thermal technology, parabolic trough concentrators (PTC) are the focus of considerable research. Conventional PTC use evacuated receivers, which contribute 30% of the solar field cost, not including significant failure (55% due to broken glass envelopes and 29% due to loss of vacuum arising due to failure of glass to metal seal). We report a non-evacuated receiver with a modular design for easier assembly and superior thermal performance for a PTC made of reflective strips of mirrored glass with a rim angle of 60 . The receiver performance is estimated using our own ray-tracing software and computational fluid dynamics (CFD) simulations using a model that we have validated with our own experimental rig. Critical parameters like the width of the mirror strip, the emissivity of solar selective coating, insulation material, and reflectivity of optical cavity walls have been analyzed in this study. A scaled-up model of the proposed novel receiver with a heat transfer fluid conduit diameter of 70 mm has been simulated to compare the performance with the commercial SCHOTT PTR ® 70.

“…Due to its simple operation and low production cost, active brazing has become a common method of heterogeneous material bonding [6, 7]. However, the active brazing is performed in a vacuum environment, and the brazing temperature is usually quite high.…”

Sn-9Zn-2Al solder alloy was used to weld silica glass and 2024 aluminium alloy with the assistance of ultrasonic wave. It can be concluded from the results that a good metallurgical bond can be formed between silica glass and 2024 aluminium alloy. The effects of different experimental parameters on the properties and morphology of soldering joints were discussed. In the use of ultrasound assisted conditions, the Al-Zn-Sn solution layer was generated on the side of the Sn-Zn-Al solder alloy and 2024 aluminium alloy due to atomic diffusion. In addition, there was an oxide layer between the solid solution layer and the solder alloy. The reason is that Al atoms can combine with O atoms under the action of ultrasonic wave, and the deposition reaction occurs to form an alumina layer. Finally, the interface structure of the soldering joint is silica glass/Sn-Zn eutectic phase, α-Al phase, β-Zn phase/Al 2 O 3 oxide layer/Al-Zn-Sn solution layer/2024 aluminium alloy.
