Help? Strontium titanates: high dielectric constant (~225-250).

[Datt]

Strontium titanates have a relatively high dielectric constant (~225-250).
Sr titanate is used for capacitors and other electronic components requiring
high dielectric constant.

Does anyone here know what these numbers mean. I don't know what a ~
signifys, related to that numerical range of resistance. Duh? Please Help?
Please clarify?

Hi,
Had one more question. If one were to look for a table or list of
insulators and the percentage insulated, with regard to piezoelectric,
dieletric, light, sound, mechanical and any other energy forces possibly
present, (I'm clueless), where or how would one begin. I'm not scientificly
inclined or learned, so I'd appreciate anything helpful or anything to
consider.
