With a total of five patents to his name, Hastert's work has advanced the understanding and application of high-transmissive materials.

Latest Patents

One of Hastert's latest patents is a method for producing a transparent polycrystalline magnesia-alumina spinel body. This innovative method focuses on creating a body with high ultraviolet transmissivity, strength, and hardness characteristics. The process involves forming a closed porosity body from a spinel powder with minimum purity characteristics. Techniques such as hot pressing and pressureless sintering are utilized, followed by a hot isostatic pressure treatment to reduce residual porosity. The resulting body exhibits high transmissivity of electromagnetic radiation and is resistant to abrasion and erosion, maintaining its integrity even after exposure to ultraviolet light.

Another significant patent is for a metallized spinel material and the method of its production. This high-transmissive spinel material is designed to have exceptional transmission capabilities in both ultraviolet and visible infrared wavelength regions. The metallization process involves applying a slurry containing metals like tungsten, molybdenum, and manganese to the substrate, followed by firing at elevated temperatures in a non-oxidizing atmosphere.
