The inorganic fiber which is dissolved in the physiological saline

摘要

(57) Abstract The fireproof fiber is disclosed. Vacuum pouring into a mold preform of the said fiber, when 24 hours being exposed with the 1260, has the coefficient of contraction of 3.5% or less. The said fiber includes ZrO₂ CaO and SiO₂, SrO, according to need, all unanticipated impurities 2 mols % are under altogether. SiO which was calculated in order to achieve the performance of the above-mentioned coefficient of contraction, the SiO₂ excessive tonnage (the above-mentioned component after crystallizing, as silicate it is defined as those which remain as tonnage of₂) 26 mols % is something which it exceeds. The desirable fiber includes, the CaO33.8 mol % under, the SiO_262.1 mol % super, furthermore the desirable fiber includes, the CaO 12.9 - 31.9 mols %, the SrO 2.6 - 15.5 mols %, the SiO₂ 63.2 - 71.3 mols %, the ZrO₂₀ - 5.4 mols %.
