SPEECH TRANSCRIPT (SEQUENCE SIX): DR. MIKE MURRAY: "As a result of Partially Stabilised Zirconia's discovery, the discovery of some of the (indistinct) toughening in this laboratory, I think its fair to say that we stand ahead of the world in that particular aspect of ceramics. There are competitive ceramics but ziconia is certainly, we know, going to be used throughout industry in many, many areas where perhaps metals have been used before."

Background: While scientists throughout the world continue to search for alternative sources of energy, the ancient art of ceramics may provide a partial answer. In Melbourne, Australia, the Commonwealth Scientific and Industrial Research Organisation's (CSIRO'S) Advanced Materials Laboratory has developed a ceramic with exceptional heat resistant properties. According to the head of the research team, Dr.Mike Murray, the ceramic, called "Partially Stabilised Zirconia" (PSZ), can replace many of the metal parts in diesel engines, such as cylinder wall liners and valve seats. The means no cooling system is required, which in itself results in substantial weight saving. The high temperature exhaust, containing far less pollution than normal, can then be used to power a turbine, which would be coupled to the drive system. Dr. Murray believes PSZ ceramics can be used throughout industry, and exports of finished products have already started. Australia is in the unique position of not only having invented the ceramic, but also being the supplier of most of the world's zircon sand, the raw material for zirconia.
