Barium titanate is a member of a large family of compounds with the general formula ABO3 called perovskites, as the crystal size of barium titanate increases and at critical crystalline size crystal structure of barium titanate transformed from cubic to tetragonal. Transformation of crystal structure is also take place at Curi temperature. Cubic structure show paramagenatic behavior while tetra...

Barium sulphate administered in association with solid food passed to the sacciform forestomach from the tubiform forestomach. However, ingested barium sulphate suspension mainly entered the hindstomach via the gastric sulcus. Barium sulphate which entered the ...
