Invention SummaryA novel method to manufacture electrochromic windows for increasing energy efficiency is under development at the University of Utah. In modern residential and commercial buildings, the most significant contributor to high heating and cooling loads is the poor energy efficiency of windows. Windows will always be inherently less effective...

Two-Phase Functionally Graded Tantalum Carbide

Invention SummaryHard materials resist wear, but are more prone to fracture. Tough materials resist fracture, but are more susceptible to wear. Generally, it is difficult to design a material that is both hard and tough. This invention seeks to balance these considerations by providing a two-phase material that exhibits both high hardness and high fracture...

Pressure-less Method for Binding Tantalum Carbides

Invention SummaryThis technology is a novel and low-cost method for binding tantalum carbides. This method is known as pressure-less sintering and only requires certain levels of heat to bond tantalum carbides. Most existing methods require both heat and pressure, necessitating more elaborate manufacturing processes. Currently, this method is used...

Direct Production of Titanium Dioxide from Ilmenite

Invention Summary Titanium dioxide is the most abundantly produced inorganic pigment in the world. It is predominantly produced by the chloride process, which employs carbo-chlorination and oxidation of titanium feed stocks at high temperature (~1300 to 1800º C). It is an energy intensive process and directly emits 550 kg CO2/ton TiO2 . A more energy...

High-Toughness Tantalum Carbide for High-Temperature Applications

Invention SummaryTantalum Carbide (TaC) is an extremely hard refractory ceramic material with high temperature resistance. Researchers at the University of Utah have discovered a form of tantalum carbide called zeta phase with three times more fracture toughness than the more common TaC form. The TaC zeta form offers high strength, high fracture toughness...
