Latest Patents

Hoff's latest patents include innovative processes for the production of potassium silicate solutions. One of his key inventions is a method for hydrothermal production of these solutions. This process allows for the direct hydrothermal production of high purity potassium silicate solutions with a high SiO₂: K₂O molar ratio. The method involves the reaction of a silicon dioxide source with aqueous potassium hydroxide solutions. It is noteworthy that the silicon dioxide source must contain a sufficient fraction of the cristobalite phase or be conditioned through heating before hydrothermal treatment. The potassium hydroxide solution used in this process typically has a concentration range of 10 to 40% by weight, and the reaction occurs in a closed pressure reactor at temperatures between 150°C and 300°C.
