摘要:
The invention relates to a method for producing package parts for optical or optoelectronic components. To this end a metal package element is bonded to a transparent package element by means of a glass solder ring, the glass solder being brought in contact with the metal package element and the transparent package element, and the metal package element being inductively heated by an alternating electromagnetic field generated by an induction coil, so that the glass solder is heated and fused in contact with the metal package element and a hermetic, preferably ring-shaped bond between the metal package element and the transparent package element being produced by fusing and subsequently solidifying the glass solder.
摘要:
The method for producing glass-coated electronic components includes processing a lead-free glass with a liquid to form a suspension, applying the suspension on an electronic component body and subsequently sintering the component body with the suspension on it. The lead-free glass contains, in % by weight, SiO2, 3-12; B2O3, 15-
摘要:
The invention relates to a method for the production of glass-coated electric components, wherein the components are, inter alia, passivated by the application of the glass. The lead-free glass used is not affected through purification and processing steps and the electric component is protected from mechanical damaging and other detrimental influences, such as impurities. Further, the method remarkably helps to stabilize the electrical properties of the components. Inter alia, a sufficient acid resistance is achieved and it results in an improvement of the expansion adjustment of the glass.

摘要:
The invention relates to a method for producing powder particles that are uniformly coated with functional groups. According to said method, a suspension of particles of a crude powder is reacted with a coating reagent that contains at least one functional group. The suspension is homogenised in an agitation mill, where the particles are reacted with the coating reagent. The powder thus obtained is suitable for use as a filler in dental materials, cosmetic compositions, pharmaceutical compositions, paints, coatings, rubber mixtures and adhesives.
