Why won't high permittivity CCTO (Calcium Copper Titanate) capacitor samples hold any charge even though LCR measurements give k in the billions+?

I am attempting to charge CCTO samples with DC or very low frequency (.01-.001 Hz) with 5V or less at approximately 150C which should have a capacitance in the Farad range. So far, I've seen no...
