Latest Patents

Arnold Van Zyl's latest patents include a method of making beta'-alumina. This invention provides a process for producing beta'-alumina by heating aluminum oxide in the presence of sodium oxide. A metal oxide dopant, such as lithium oxide, magnesium oxide, zinc oxide, cobalt oxide, nickel oxide, or iron oxide, is dispersed in a cubic-close packed aluminum oxide or its precursor. The starting mixture is then calcined by heating to temperatures between 250°C and 1100°C in an oxygen-containing atmosphere. Following this, sodium oxide is dispersed in the calcined mixture, which is heated above 1100°C to produce beta'-alumina. His second patent also focuses on a method of making beta'-alumina, involving the dispersion of sodium oxide and a spinel stabilizer in a precursor of aluminum oxide, followed by heating to convert the precursor into beta'-alumina.
