Tin oxide fiber and a process for producing the same

摘要

A tin oxide fiber expressed by the general formula Sn(1-y)ZyO2 (I) wherein Z is a metal element of the Group V of the periodic table, and y is 0 to 0.3, having a diameter which is greater than 1 mu m or having a length which is greater than 3 mm and having an aspect ratio which is greater than 10. This fiber is process for producing a tin oxide fiber comprising spinning an alcohol solution of a tin compound soluble in alcohol, or spinning an alcohol solution of said tin compound and a compound of a metal of the Group V of the periodic table that is soluble in alcohol, followed by heating.
