METHOD OF MANUFACTURING LEAD-ALUMINOSILICATE GLASS BY SOL-GEL METHOD

摘要

The present invention relates to a method for producing lead aluminosilicate glass which can be used for semiconductor surface protection by the sol-gel method.;In the method for producing lead aluminosilicate glass using the sol-gel method of the present invention, a lead-based raw material, an aluminum-based raw material and deionized water are mixed and stirred to dilute a mixed aqueous solution and a silicon-based raw material to alcohols to form an alkoxide solution, respectively. Step 1; Stirring and mixing the alkoxide solution with stirring the mixed aqueous solution, followed by two steps of pouring ammonia water to react; Three steps of stirring until the treatment is uniform; Leaving the treated material to precipitate and then removing the clear solution at the top to obtain a glass gel solution; And it comprises a five steps of drying the glass gel solution, heat drying in an oxygen atmosphere.;According to this method, lead aluminosilicate-based glass for semiconductor bonding protection can be produced economically high purity and finer than conventional commercial glass powder.
