摘要:
The present disclosure relates to a glass composition as well as a glass powder. The disclosure also relates to the use in the dental field, e.g. as dental material such as dental filling or dental restauration material, in particular as or for the production of a glass ionomer cement, for example for the treatment and/or for the filling of cavities in human and/or animal teeth and/or for tooth restoration.
摘要:
The disclosure relates to a bond produced with an at least partially crystallized glass, such as a metal-to-glass bond, in particular a metal-to-glass bond in a feed-through element or connecting element, and to a method for producing such a bond, in particular in a feed-through element or connecting element. The at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.
摘要:
The invention relates to a radiopaque glass having a refractive index nd of 1.480 to 1.561, this glass, apart from impurities at most, being free from SrO and PbO. The glass is based on the SiO2, Al2O3 and B2O3 system. The radiopacity can be adjusted using Cs2O in particular in combination with BaO and/or SnO2 optionally in conjunction with fluorine. The glass may be used in particular as dental glass or as optical glass.
摘要:
The amorphous, or at least partially crystalline, glass-based joining material is suitable for high-temperature applications, particularly in fuel cells and/or sensors. In addition to SiO2 and B2O3 as glass formers, the joining material similarly contains BaO and CaO, whereby the amount of Al2O3 is limited. The joining material has a coefficient of linear thermal expansion of at least 7.0·10−6 K−1 in a range of 20° C. to 300° C. The joining material can be used for joining ferritic high-grade steels and/or chromium-containing alloys and/or ceramics, such as stabilized zirconium oxide and/or aluminium oxide.
摘要:
A vitreous or glass-ceramic jointing material, which has a coefficient of thermal expansion α(20-750) of ≧7·10−6 K−1 and is free of BaO and SrO except for at the most impurities and is suitable for producing joint connections between chromium-containing alloys or chromium-containing steels.

摘要:
The sodium-resistant joining glass (1) is substantially free of ZrO2 and is based on a SiO2—B2O3—Na2O—Al2O3 glass system. It is suitable for producing a joint of a metal and/or ceramic component with a further joining component (2, 3, 4) using the joining glass (1). Feedthrough-devices (20) using the joining glass (1) as fixing material are also disclosed.
