Abstract

The work is devoted to production of heat-insulating materials from refractory fibers of aluminium oxide and silicon. Refractory fibres are prepared by sol-gel technology from highly viscous solutions based on precursors of water-soluble aluminium salts with addition of fibre-forming component to the solution. Methods of scanning differential calorimetry and gravimetric studies during heating have studied the processes of changing the composition and structure of oxide fibers. Mechanical properties of sealing cords with refractory fiber core were tested.
