    摘要: The present invention is directed to a coating composition and its employment in a metallization process that facilitates bonding of brazing filler metals to treated refractory surfaces, such as ceramics. The coating can be applied in preselected areas of the refractory surface to define the target area for brazing. It is believed that when compositions of the present invention are employed with brazing or soldering filler metals, strong bonds between two non-metallic refractory bodies, or between a non-metallic refractory body to ferrous and non-ferrous metal can be attained. In one embodiment, the present invention is a coating composition applied to a refractory material prior to brazing, the composition being comprised of a group IVB transition metal component selected from the group consisting of a group UVB transition metal, a hydride thereof, mixtures of group IVB metals and/or hydrides thereof, a binder material, and a fluid carrier. For example, the group IVB transition metal component may be a group IVB transition metal selected from among titanium, zirconium, hafnium, and thorium, hydrides of these group IVB transition metals, and mixtures of these group members. In one embodiment, the group IVB transition metal component is titanium, titanium hydride, or mixtures thereof.

    摘要: A method for forming a thick film pattern is provided which can easily perform pattern formation even when a photosensitive paste containing a powdered conductor at a high content and having a low optical transmittance is used and which can form a thick film pattern having a rectangular cross-section and superior high-frequency transmission characteristics. In addition, a photosensitive paste used therefor is also provided. The thick film pattern having a predetermined shape can be formed by the steps of determining the photocurable depth d of a photosensitive paste; coating with the photosensitive paste in consideration of the photocurable depth d so as to form a photosensitive paste film having a predetermined thickness t; exposing the photosensitive paste film; and developing the exposed photosensitive paste film. Preferably, the coating with the photosensitive paste is performed so that the relationship between the photocurable depth d of the photosensitive paste and the thickness t of the photosensitive paste film satisfies the equation tnulld.
