Paste, paste for sealing, paste for forming conductor layer, and method for producing low melting point composition powder and paste

摘要

Problem to be solved: to provide a paste containing a low melting point composition powder which is well fluidized by heat treatment in a low temperature region and capable of forming a highly reliable sealing or conductive layer by cooling solidification, and a method of manufacturing the same.Solution: a paste comprising an organic solvent and a low melting point composition powder, and the low melting point composition powder is formed from a crushed crystallized glass, and the crystallized glass is a crystallized form of glass having a glass transition point at a temperature of less than 100.degree. C.A method for producing a low melting point composition powder containing a step of crystallizing glass having a glass transition point of less than 100.degree. C. and crystallizing the crystallized glass and pulverizing the crystallized glass, and making a paste comprising the step of mixing the powder with an organic solvent Construction method.No selection
