What the hell do those "risk and safety phases" mean? 76.111.88.167 03:07, 31 October 2007 (UTC)

What is the accepted value for dielectric constant? Oanjao (talk) 20:17, 25 August 2009 (UTC)

Hans Meissner ("Demonstration of Displacement Current," American Journal of PhysicsVolume 32, Issue 12 [December 1964], pp. 916) says the dielectric constant is 2800. This value should be included in the article. I imagine it's known with more precision now. JKeck (talk) 18:31, 19 January 2011 (UTC)

This crystal structure should be tetragonal not cubic, after all it is birefringent. —Preceding unsigned comment added by 68.228.190.197 (talk) 22:46, 23 December 2009 (UTC)

Thanks, off course, correcting. Materialscientist (talk) 00:16, 24 December 2009 (UTC)

"Fully-dense nanocrystalline barium titanate has 40% higher permittivity than the same material prepared in classic ways.[3]" I've checked the article in question, which discusses microwave enhanced hydrothermal synthesis and its effect on size, shape, etc. But there is no mention whatsoever concerning the permittivity, dielectric constand, etc. being affected. One would assume it would, since the ratio of cubic to non-cubic will change. But that is never addressed in this paper.Broklynite (talk) 21:08, 17 August 2010 (UTC)

Ref 11 appears to be on the standard Fe-doped LN, not barium titanate. Not aware of any use of this latter material in similar applications Wikibearwithme (talk) 21:43, 15 November 2015 (UTC)
