AbstractThis study involved the determination of the effects of composition and microstructure on the fracture toughness and susceptibility to environmentally enhanced crack growth of several ceramic materials used in multilayer capacitors. Indentation-fracture procedures were used to measure KIC as well as to assess the possible effects of internal stresses on the fracture behavior of these materials and to correlate dielectric aging phenomena with strength. The environmentally enhanced crack growth behavior of these materials was determined by conducting dynamic fatigue tests in water.

Vegetation Samples

Many analysts use a wet or dry oxidation treatment prior to determination of minor and trace elements in non-fossilised vegetation. This stage is often unnecessary for XRFS since the technique is sufficiently sensitive for many purposes to permit the analysis of unashed material. Indeed, inaccurate results may be obtained if volati1es are lost, if no correction is made for loss on ignition, or if such correction is of large magnitude.
