Vaccum material reference list

Has anybody experience with contamination in vacuum (outgassing) coming from
capacitors (ceramic, electrolytic, etc.) and also different ceramic types like NPO,
X7R, Z5U?
And also how does capacitance change below the specified minimum operational
temperature (normally -55 degC)?

Gustavo.
