Babbling gibberish, word salad.

"Quartz glass has a very high dielectric strength but a very low electric
conductivity, even at high temperature, high voltage and high frequency,
nearly without electric loss in the range of the frequencies applied.
Therefore quartz glass is an excellent high temperature dielectric
material."

What is the cause: polarisation or electrostriction or the both?
