- Title
Study of Chemical and Technological Bases for Preparing Aluminosilicate Refractories Based on Fly Ash.

- Abstract
The possibility of using fly ash from thermal power plants to prepare fused mullite powder with subsequent use as a filler for aluminosilicate refractories is investigated. Introduction of orthophosphoric acid as a binder to a raw material charge provides a reduction in firing temperature of fireclay refractories by 150 – 200°C, which is an important factor in the contemporary organization of production using energy-saving technology. The products obtained in accordance with the requirements of GOST 390–2018 correspond to fireclay products of the ShV grade and are recommended for use in lining heating units.
