Latest Patents

One of her latest patents involves the preparation of sintered cordierite glass-ceramic bodies. This invention discloses a procedure that utilizes three all-natural starting materials: white sand, kaolin clay, and magnesite. These materials are combined in specific relative amounts to create a mixture of silicon, aluminum, and magnesium oxides. Upon melting at temperatures between 1500-1550°C, the raw materials form a transparent brown glass. After solidification through quenching, the glass is crushed into grains with a median particle size of less than 65 microns. These grains are then consolidated to form a green body for sintering. The sintering process, conducted at temperatures ranging from 1000°C to 1375°C for 2 to 5 hours, results in glass-ceramic bodies that exhibit properties suitable for various technical fields, including cookware, water filtration devices, and electronics.
