PROCESS OF MAKING A HIGHLY DISPERSED MIXTURE OF CARBON BLACK AND SILICIC ACID

摘要

A highly dispersed homogeneous mixture of activated carbon black and activated silicic acid is formed by subjecting gaseous silicon monoxide or a mixture thereof with a gaseous metal oxide to the action of a gaseous oxidizing agent and passing substantially simultaneously a material that forms carbon black upon decomposition into the oxidizing zone or into the stream of gas right above the oxidizing zone.
