With a total of 4 patents to his name, Bult's work has had a considerable impact on the industry.

Latest Patents

Bult's latest patents include a method for the zone refining of gallium. This innovative process involves refining impure gallium in a stationary, vertical, double annulus refiner. The gallium is contained between walls made of a material that does not impart impurities. A cooling fluid circulates through a second annulus, and the gallium is zone refined by moving through the ingot with molten zones formed by radio frequency waves. This method allows for the recovery of refined gallium with purities between 79 and 89. Another significant patent involves the purification of cadmium (Cd) and tellurium (Te) through multiple-pass zone refining. This process improves the purity of Cd and Te, resulting in enhanced ductility and higher yields of refined materials.
