Title: Eva Hoelzel: Innovator in Glass Ceramics
Introduction
Eva Hoelzel is a prominent inventor based in Ober-Olm, Germany. She has made significant contributions to the field of glass ceramics, holding a total of 4 patents. Her innovative work focuses on enhancing the properties and applications of glass materials.
Latest Patents
One of her latest patents is titled "Lithium-aluminosilicate glass ceramic with high keatite content and structural member made thereof." This invention involves a lithium-aluminosilicate glass ceramic that is transformed through a suitable heat treatment into a glass ceramic comprising at least 80 vol.-% of keatite mixed crystals. This material is particularly useful for creating optical or mechanical high-precision parts that exhibit high temperature resistance, stability, and compatibility with metals that have a small coefficient of thermal expansion, such as Invar®.
Another notable patent is the "Method for the forming of glass or glass ceramics." This process describes how to form glass or glass ceramics by molding a starting glass into a specific shape, which is then transformed through heat treatment into a keatite glass ceramic. This innovative method allows for the preparation of formed bodies from blank parts by sagging under gravity at temperatures above the glass transition temperature.
