Title: Alexander Holzel: Innovator in Porous Glass Membrane Technology
Introduction
Alexander Holzel is a notable inventor based in Mainz-Finthen, Germany. He has made significant contributions to the field of materials science, particularly in the development of porous glass membrane tubes. With a total of 2 patents, his work has implications for various industrial applications.
Latest Patents
Holzel's latest patents focus on the production of tubular glass membranes. The first patent describes a process for creating these membranes with wall thicknesses ranging from 5 to 30 microns and reproducible pore sizes between 11 A and 50 A. The process involves drawing alkali borosilicate glass into discrete hollow tubes, which are then immediately cooled. Following this, the tubes undergo thermal treatment to achieve phase separation into a coherent silicon dioxide phase and a boron oxide phase rich in alkali borate. The boron oxide phase is subsequently leached out using mineral acid. This innovative method allows for the subsequent treatment of the tubes to create enlarged or reduced pores, asymmetric pores, and coated surfaces.
