High silica fiberglass cloth is made of high silica yarn woven into cloth, with plain weave and satin weave. Its silicon oxide content is from 96% to 98%, and it can resist up to 1050 ℃ continuously. Its thermal conductivity is lower, thus good resistance to high temperature. It is inert to most chemicals and has good corrosion resistance to compounds, corrosive minerals, and weakly alkaline molten alloys at high temperatures.
