Highly Porous Granulated Corundum Filler of Alumina-Foam Polystyrene Mixture. Part 9. Physicotechnical Properties of Porous Corundum Granules and Fillers Based on Them1

  • V. N. SokovEmail author

Results are provided for a study of the strength properties of both individual fractions and also mixtures based upon them. It is established that in order to reduce filler electrical conductivity there should be a reduction in granule diameter or creation of denser polydispersed compositions. Introduction into a charge composition of corundum filler with a size of 60 μm increases granule thermal stability.
