ABSTRACT:
A glass-enclosed integral glass and ceramic filter unit is described for filtering sulfuric acid or other liquid solutions which do not attack silica and in which the sole communication between a first and a second chamber within a totally enclosing glass housing is through the pores of a ceramic filter membrane. This microporous ceramic membrane is connected to the interior of the glass housing by a glass seal wall member fusion bonded thereto advantageously providing an integral filter unit without any mechanical pressure seals or gaskets or other sealing elements having joints through which finely divided particulate matter could by-pass the filter membrane. To accommodate the significant difference between the coefficient of thermal expansion of the ceramic filter membrane, which is described as microporous porcelain, and that of the glass housing, the glass sealing wall member is formed of a plurality of bands of glass having different coefficients of thermal expansion which are graded in sequence for providing a progressive transition while achieving an integral structure.
