1. The crystal fiber can be divided to A72(DNX-1400), A80(DNX-1500), A95(DNX-1600), according to the different alumina content.
2. The service of the crystal fiber can arrive at least 1400 due to the micro crystal structure content. A95 fiber can be used higher than 1600oC.
3. The crystal fiber with low thermal conductivity, low thermal storage, stable chemical performance, good corrosion resistance and thermal shock resistance, good sound insulation etc, can be used to produce mixed fiber insulation board, felt and deformed products, renforced material for piston, furnace lining etc.
