The novel ceramic fiber provided by the invention has the following technical effects: 1) the fiber is high in strength which is greater than 2GPa; 2) the fiber has a good high-temperature performance.
Description
Technical field
the present invention relates to a kind of new ceramics fiber, belong to chemical fiber field.
Background technology
Ceramic fiber is a kind of fibrous light refractory materials, have lightweight, high temperature resistant, Heat stability is good, thermal conductivity are low, specific heat is little and the advantage such as mechanical resistant vibrations, be thus obtained in the industry such as machinery, metallurgy, chemical industry, oil, pottery, glass, electronics and apply widely.Rising steadily in recent years due to global energy price, energy-conservationly become China national strategy, in this context, the ceramic fiber of the energy-conservation 10-30% of reaching such as resistance to material more traditional than insulating brick and pouring material etc. obtains more wider application at China, and development prospect is very good.But the performance of existing ceramic fiber is perfect not enough, can not large-scale promotion application.
