I am a research scientist specializing in low-temperature mineral synthesis. In 1972 I founded the private research company CORDI (Coordination and Development of Innovation), and, in 1979, the Geopolymer Institute, both in France. At the Geopolymer Institute a new branch of chemistry that I named ization. I currently have more than twenty-five international patents for geopolymeric products and processes. My products are made... by large manufacturers. The products have many diverse applications.
