摘要
Open-pored sintered glass is produced by conventional processes but, at pore volumes of more than 60%, the resulting tensile bending strengths are too low for an application as a filter medium. A further disadvantage for filtration is the wide distribution of the pore size and the structuring of the internal surface of the pores. The novel process is intended to provide open-pored sintered glass with large open pore volume, high tensile bending strengths and good flow rates. …??In this process, starting granules of finely granulated glass powder, coarsely grained salt powder and binder are first prepared. 5 to 20% by weight of fine-grained glass powder is then added to these starting granules and this mass is subjected to shaping. The shaped product as formed is heated to the sinter temperature of the glass and sintered, and the salt is then washed out of the sintered glass. …??Production of open-pored sintered glass for filters.
