Entropic rejuvenation of thin glass products by liquid metal immersion

Project description

A new way to thin out strong glass

Glassmaking was discovered some 4 000 years ago, or more. Today, glass is omnipresent – from architecture to automotive windshields and solar panels on rooftops. While the manufacturing of strengthened glass has matured, there are limitations in terms of glass thickness. The EU-funded enjulii project is targeting the commercialisation of a novel post-processing method for thin-walled glass products. This new technology is expected to decrease accessible glass thickness by applying an efficient technology that will enable significant reductions in embodied energy, CO2 and product weight. It will also result in the strengthening of non-sheet glass products (fibres, rods and tubes) for a range of fields from pharmaceutical packaging to functional lighting and illumination.

Objective

Mechanical performance and consumer product safety have been major drivers for glass research and innovation. Strengthened glass products are omnipresent in daily life, from rooftop windows and automotive windshields to solar modules, partition walls and covers for handheld electronic devices. However, thermal strengthening as today’s most widespread method for enhancing the strength and reliability of glasses has reached maturity, leaving fundamental restrictions in terms of applicable glass thickness and type. These limitations do not only prevent the further development of sustainable and efficient lightweight glass structures, but also exclude the process from many of the most prolific specialty glass applications. The present proposal targets market readiness and commercialisation of a novel post-processing method for thin-walled glass products which overcomes the limitations of thermal strengthening by achieving a tenfold decrease in accessible glass thickness and/or coefficient of thermal expansion. By this, we will break ground for applying an otherwise intriguingly efficient technology to thin-walled glass products and glass compositions which were previously outside of the process’s capabilities. This will not only enable significant reductions of embodied energy, CO2 and product weight, but also lead to new opportunities in the strengthening of non-sheet glass products, e.g. fibres, rods and tubes on fields such as pharmaceutical packaging, injectors, functional lighting and illumination, and specialty glass substrates.
