Firing up the furnaces.
A new type of fibrous insulation that takes advantage of the high melting point of the ceramic zirconium oxide (zirconia) may enable furnaces to operate continuously at temperatures as high as 2,000[deg.]C. Existing fiber-lined furnaces run at 1,700[deg.]C or less. Higher-temperature furnaces would allow the development of new alloys, ceramics and composites that contain larger concentrations of metals with very high melting points. This insulating material was developed by George E. Wrenn Jr. and his colleagues at the Oak Ridge (Tenn.) Y-12 Plant, a manufacturing complex that produces components for nuclear weapons.
