Title: Innovations of Mark V Parish in Polycrystalline Alumina
Introduction
Mark V Parish is an accomplished inventor based in Hopkinton, MA (US). He has made significant contributions to the field of materials science, particularly in the development of polycrystalline alumina articles. With a total of 2 patents to his name, his work focuses on enhancing the properties of alumina for various applications.
Latest Patents
Mark V Parish's latest patents include innovative methods for manufacturing polycrystalline alumina that exhibit improved transmission in the infrared region. One of his notable inventions involves forming polycrystalline alumina articles by providing a powder of substantially alpha phase alumina with a grain size of up to about 1 µm. This process includes dispersing the powder in a liquid to create a slurry, removing excess liquid to form a body, and then heating the body to achieve a densified state. The densified body is hot isostatically pressed to produce an article with a density of at least about 99.9% of theoretical density, with optional annealing performed in an inert, dry gas. His work also emphasizes achieving a percent real in-line transmittance within about 2% of sapphire at selected wavelengths, along with improved mechanical properties such as thermal shock resistance and hardness, which are beneficial for armor applications.
