FIELD: chemistry.
SUBSTANCE: invention relates to an inorganic fibre having a radiation resistance property. Inorganic fibre contains SiO2, Al2O3, CaO and Fe2O3 as components, where weight percentages of components in terms of oxide in inorganic fibre are as follows: general content SiO2 and Al2O3 ranges from 40% by weight to 70% by weight, the ratio being Al2O3/(SiO2+Al2O3) (weight ratio) is in range from 0.15 to 0.40, content of Fe2O3 ranges from 16 % by weight to 25% by weight and content of CaO ranges from 5% by weight to 25% by weight.
EFFECT: invention makes it possible to create inorganic fibre with suitability for spinning from melt and resistance to radiation.
