After this, carbon black (1.25 vol.%) was added. Mixing was conducted by using a ball mill and stainless steel balls for 30 min. After mixing, the paste was placed in a vacuum chamber (which involved a mechanical vacuum pump) without heating for the pur-pose of air bubble removal. The thixotropic paste contained 2.4 vol.% carbon black.Web
