'Steel-like' ceramic is toughest yet
Article Abstract:
Zirconia-based ceramics in the form of feedstock powders have been formed by processing gas plasma, with twice the toughness and five times the green strength. Tioxide Specialties' new plant produces zirconia powder by burning oxygen and zirconium tetrachloride vapour at high temperature in a plasma torch. The powder is compositionally zoned and has particles of only 70 nm in size. The powder is surrounded in a 10 nm coating of yttria. It is a nano-composite. The fine structure of the powder increases its strength by 10%, and raises its toughness by up to twice as much. The powder also resists high pressure steam ten times as well.

Intelligent sensors break cost barrier
Article Abstract:
Sensor products with current and innovative technology are reviewed with respect to cost. Minnesota's Nonvolatile Electronics Inc. has created Giant Magnetoresistive Ratio materials which are used in low cost, highly sensitive and intelligent sensors with a changing resistance to register changes in the magnetic field. Nonvolatile are currently working with others to at paint sprayer and automobile applications.
