It was established that the circumferential velocity maintained during the centrifugal casting process has a significant effect on the porosity of the castings. The effect of the rheological behavior of the original HCBS is also significant. We carried out a comparative analysis of the rheological properties of the HCBS of fused quartz having different pH values with the parameters of their centrifugal casting and the porosity of the obtained castings. As in the case of slip casting, unfired quartz ceramics were obtained according to the method of centrifugal casting. These ceramics exhibit high levels of mechanical properties after undergoing a hydrothermal treatment or a strengthening treatment in alkaline solutions. The possibility of using the method of centrifugal casting for shaping the refractories based on the casting systems containing a granular filler (the keramobeton-type systems) was established.
