IT is well known 1 that the dielectric behaviour of barium titanate and some mixed crystals of it with related compounds is quite different from most other materials (see accompanying illustration).

This week, China’s domestic manganese-based battery materials market has shown a differentiated operation trend. The price of battery-grade manganese tetroxide has slightly declined, the price of ...

In contrast to the typical price declines seen during the traditional spring festival low season from January to February in previous years, China’s domestic manganese sulfate market has recently ...

THE growth of barium titanate single crystals and the ferro-electric behaviour of their pseudocubic modification have been described earlier 1, 2, and more detailed data can now be given.

Barium (Ba) is a trace element which occurs predominantly as barite mineral (BaSO 4) in the marine environment. Previous work suggests that barite concentrations are related to the organic carbon flux ...
