The present invention relates to a glass, in particular a glass for the joining of glass panes for the production of vacuum insulating glasses at processing temperatures ≤420° C., to the corresponding composite glass, and to the corresponding glass paste. Moreover, the present invention relates to a vacuum insulating glass produced using the glass paste according to the invention, to the production process thereof, and to the use of the inventive glass and/or composite glass, and glass paste. The glass according to the invention is characterized in that it comprises the following components, in units of mol-%: V2O5 5-58 mol-%, TeO2 40-90 mol-%, and at least one oxide selected from ZnO 38-52 mol-%, or Al2O3 1-25 mol %, or MoO3 1-10 mol-%, or WO3 1-10 mol-%, or a combination thereof.
A joining glass comprising the following components in units of mol-%:
A composite glass comprising a glass according to claim 1 and 1 to 25 wt-% of at least one filling agent selected from the group consisting of zirconyl phosphates, dizirconium diorthophosphates, zirconium tungstates, zirconium vanadates, Zr2(WO4)(PO4)2, aluminum phosphate, cordierite, eucryptite, keatite, (Hf,Zr)(V,P)207, NaZr(PO4)3 and alkaline earth zirconium phosphate.
A process for producing a vacuum insulating glass, comprising:
A joining glass comprising the following components in units of mol-%:
