Title: Howard L McCollister: Innovator in Glass Ceramic Technology
Introduction
Howard L McCollister is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of glass ceramics, holding a total of 8 patents. His work focuses on developing advanced materials and processes that enhance the performance and durability of glass-to-metal seals.
Latest Patents
One of McCollister's latest patents is a method of processing 'BPS' glass ceramic and seals made therewith. This invention involves a glass ceramic composition that includes specific weight percentages of SiO₂, LiO₂, Al₂O₃, K₂O, P₂O₅, B₂O₃, and ZnO. The processing steps include heating the glass composition in a belt furnace, holding it at a specific temperature to create cristobalite nuclei, and cooling it at a controlled rate to promote crystallization. This innovative process results in a glass ceramic with a high coefficient of thermal expansion, enabling the fabrication of hermetic glass ceramic-to-metal seals, particularly for nickel-based and stainless steel alloys.
Another significant patent involves titanium sealing glasses and seals formed therefrom. This invention provides alkaline-earth lanthanoborate sealing-glass compositions that are useful for forming hermetic glass-to-metal seals with titanium and its alloys. These compositions are particularly valuable for applications requiring exposure to moisture, such as lithium batteries and implanted biomedical devices.
