Effect of Heat Treatment on Specific Surface Area of Si-C-O Fibers

摘要：

　　In this paper,effect of heat treatment on the SSA of Si-C-O fibers was investigated and morphologies of the treated fibers were studied using SEM.The results revealed that weight loss was proportional to the treatment time at 1573K and the specific surface area (SSA) increased sharply when the weight loss reached above 6wt%.A rough and porous ceramic fiber with SSA of 23.76m2/g could be obtained at the weight loss of 9.1 wt%,as a result of the treatment at 1573K for 32h.
