Abstract
The joining of glass with metal plays an important role in various applications including vacuum tube, Solid Oxide fuel cell, electronics component, parabolic trough receiver tube (PTRT).The presented research is focused on the development of novel glass-metal joint for PTRTs. The initial aim of present investigation was to select a suitable glass-metal joint combination on the basis of wettability, surface roughness, pre-oxidation time, microstructural and X-ray diffraction studies. Later, an unmatched glass-metal joint between borosilicate glass and austenitic stainless steel SS 304 was developed after selecting the suitable glass-metal joint combination. 40SiO2-54B2O3-4Na2O-2Al2O3 material was used as the glass sealant to join the SS304 metal ring and borosilicate glass tube. The chemical compositions of glass sealant were investigated by changing SiO2/B2O3 ratio by using statistical design of experiment approach for SiO2-Al2O3-B2O3-Na2O system. The effect of SiO2/B2O3 ratio in glass sealant on wettability, glass transition temperature Tg and crystallization temperature Tc, thermal conductivity, adhesion and density were studied.
