Both can be used in place of 400-, 325- or 200-mesh flint, but if a glaze recipe calls for 200-mesh flint, 325-mesh flint would be the best option. Some glazes are sensitive to finer grind materials. The smaller mesh materials can increase glaze melt—increased surface area produces more of a reaction with other glaze materials—which might ...

A recent trend in the study on piezoelectric and/or pyroelectric ceramic compounds is the use of lead-free materials. The other trend is the use of grain orientation techniques as the ceramic fabrication methods. Recently, bismuth layer-structured ferroelectrics (BLSF), which form one of BO6 octahedral ferroelectric groups, have been ...
The classical view of the structural changes that occur at the ferroelectric transition in perovskite-structured systems, such as BaTiO3, is that polarization occurs due to the off-center displacement of the B-site cations. Here, we show that in the bismuth sodium titanate (BNT)-based composition 0.2(Ba0.4Sr0.6TiO3)–0.8(Bi0.5Na0.5TiO3), …
