摘要

Beta silicon carbide whiskers in the form of long staple wool (1 - 10microns by 1/2inch - 1inch length) have been grown by flowing a H2,CO, CH4,and N2gas mixture through a reactor containing a silica source,and five pounds of the output whisker product have been delivered. Growth studies have been made in the temperature range of 2300to 2800F in growth times ranging from 4to 24hours. The reactor consisted of a 20KW furnace containing a quartz muffle. Gas composition,collector geometry,and materials have been studied to enhance the type and quantity of silicon carbide wool produced. (Author)
