Title: Kozo Maeda: Innovator in Crystallized Glass Technology
Introduction
Kozo Maeda is a prominent inventor based in Hyogo, Japan. He has made significant contributions to the field of glass technology, particularly in the development of crystallized glass compositions. With a total of four patents to his name, Maeda's work has advanced the capabilities of sealing materials used in various high-temperature applications.
Latest Patents
Maeda's latest patents include innovative sealing glass compositions. One notable patent discloses a sealing glass composition that transforms into a crystallized glass when fired at temperatures between 900-1150°C. This composition is designed to have a thermal expansion coefficient of 80-110×10/°C in the range of 50-850°C. Importantly, it is substantially free of both boron oxide and barium oxide, comprising SiO (43-53 mol %), CaO (12-33 mol %), MgO (12-33 mol %), LaO (1-7 mol %), and ZnO (0-4.5 mol %).
Another significant patent reveals a sealing glass composition that does not contain boron oxide or aluminum oxide. This high-strength, high-expansive crystallizing glass can withstand high temperatures of at least 950°C. The composition includes SiO (40-55 mol %), BaO (18-35 mol %), TiO+ZrO (0.1-10), ZnO (0-15), CaO (0-20), MgO (0-9), SrO (0-5), and LaO (0-2). When fired as glass powder at temperatures of 850-1050°C, it transforms into a crystallized glass with a thermal expansion coefficient of 90-150×10/°C in the range of 50-850°C.
