Abstract
With regard to HFO-1234yf mixed with CO 2 as a buffer gas, this paper describes dielectric breakdown properties such as an electron attachment coefficient and a critical reduced electric field strength E cr /N at 300–3000 K. First, this paper covers predominant molecular products through thermal dissociation and combination reactions for 20%HFO-1234yf/80%CO 2 gas mixture. Secondly, dielectric breakdown properties of the mixture in consideration of the predominant gaseous molecular products are described to show that E cr /N is 87–100 Td at 300–3000 K.
