Latest Patents

One of Weaver's latest patents focuses on silica powders for powder evacuated thermal insulating panels. This invention utilizes generally spherical and porous silica particles with a median size of less than about 100 nanometers in diameter. The powders have a pour packing density of about 0.4 to 0.6 g/cm³ and an external surface area ranging from about 90 to 600 m²/g. The silica powders are created by reacting a tetraakyl silicate with ammonia and water in an alcohol solvent. After the reaction, the solution is distilled to remove ammonia and recover the alcohol. The resulting aqueous slurry is dried, ball-milled, and dried again to produce silica particles with defined internal and external porosity. The unique characteristics of these silica particles provide powder evacuated thermal insulating panels with significantly higher R-values compared to previously known silica powders.
