The Submicron Grinding of BaTiO3 by Ball Milling [Translated]†
The submicron grinding of BaTiO3 powder was studied by a ball mill with small alumina balls of 0.75 mmΦ to 30 mmΦ. BaTiO3 clinker, which was obtained by calcining an equimolar mixture of TiO2 and BaCO3, was preground to 1.8 micron. Submicron grinding of the BaTiO3 powder was possible by ball milling...

| description | The submicron grinding of BaTiO3 powder was studied by a ball mill with small alumina balls of 0.75 mmΦ to 30 mmΦ. BaTiO3 clinker, which was obtained by calcining an equimolar mixture of TiO2 and BaCO3, was preground to 1.8 micron. Submicron grinding of the BaTiO3 powder was possible by ball milling with several mmΦ balls. For a ball diameter of 2 mm, the specific surface area was maximized.An attempt was made to represent the specific surface area in terms of volume per ball and total surface area of used balls, and the following experimental equation with a time term was obtained,In(SS) = -0.247lnr3 - 0.738/r + 0.429 lnt + 1.57where SS is the specific surface area, r is the ball radius, and t is time. The multiple correlation coefficient R was found to be 0.982 when calculated by computer.† This report was originally printed in J. Soc.
