Read MoreJan 01 2011 The hexagonal phase produced by high-energy ball milling of RbNbWO 6 transforms back to the pyrochlore structure upon heating to 773 K in air. A similar phase was obtained by ball milling the mixture RbNbWO 6 WO 3 but in this case the stoichiometric hexagonal tungsten bronze compound thus obtained remained stable up to 1273 K.

Read MoreJun 15 2012 1. As the name suggests the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron hardened steel silicon carbide or tungsten carbide balls are made to rotate inside a mill drum. 2. The powder of a material is taken inside the steel container.

Loading of a ball mill by the material is proportional. The more material is fed into the mill the higher grinding productivity. But at some point there is too much material in the mill and the material is not grinded any more the grinding productivity decreases abruptly down to zero and the mill blockage takes place see Fig. 2. ...

The use of the pyrochlore phase in the photoelectrode had a positive effect improving the efficiency of the pure TiO 2 cells. The efficiency increased by between 2.32 and 3.16 when pure TiO 2 was replaced with a mixture of rutile TiO 2 and pyrochlore Tm 2Ti 2O 7 so the controlled use of a pyrochlore
