The present disclosure provides a method for coating a composite structure, comprising forming a first slurry by combining a glass frit comprising a first phosphate glass composition with a first carrier fluid comprising an acid aluminum phosphate, wherein the ratio of aluminum to phosphoric acid is between 1 to 2 and 1 to 3, applying the first slurry on a surface of the composite structure to form a base layer, and heating the composite structure to a temperature sufficient to adhere the base layer to the composite structure.

The present invention relates to an anisotropic glass containing, in terms of mol % on the basis of oxides, P.sub.2O.sub.5 in a content of from 45 mol % to 57 mol %, two or more kinds of alkali metal oxides selected from the group consisting of Li.sub.2O, Na.sub.2O, K.sub.2O, Rb.sub.2O, and Cs.sub.2O in a total content of from 30 mol % to 54 mol %, and at least one polyvalent element oxide other than P.sub.2O.sub.5 in a total content of from 0.1 mol % to 20 mol %, and having a birefringence of 30×10.sup.−6 or more.

A marking composition for forming marks or indicia on a substrate is provided for laser marking applications. The composition includes a glass frit, a carrier, and absorber particles. The glass frit includes alkali metal oxides, glass forming oxides, and one or more transition metal oxides. The glass frit is devoid of at least one of bismuth and zinc.

The present invention relates to an apparatus for manufacturing vacuum glass. An apparatus for manufacturing vacuum glass, according to an embodiment of the present invention, includes an exhaust finishing frit inserted into an exhaust hole of a plate glass assembly so as to seal the exhaust hole in an exhaust process. In addition, the exhaust finishing frit comprises: a frit body having a body top part on which a cap frit is placed; a depressed portion which is upwardly depressed from the bottom of the frit body; and an exhaust guide part which is formed to penetrate the outer circumferential surface of the frit body. Thus, it is possible to prevent bubbles from being generated in the exhaust finishing frit during a finishing process.

An electronic device housing, an electronic device and a compound body are provided. The electronic device housing comprises a frame; a sealing layer, disposed on at least a part of an outer surface of the frame, and including a plurality of sub-sealing layers laminated in sequence; and a back case, attached to the frame by the sealing layer, wherein two adjacent sub-sealing layers have different compositions.
