The effect of the addition of nanoscale SiO2 on the physical and mechanical characteristics and durability of an industrial batch of refractory products
View through CrossRef
The physicomechanical properties and structure of mullitecorundum unformed refractories were investigated and tests of a pilot batch of refractory products for various purposes were carried out. The effect of the addition of nanoscale SiO2 (1 wt. %) on strength, structural (density, porosity) and operational characteristics of unformed refractories. The results show that this additive contributes to the formation of a structure with high apparent density and compressive strength (2,93 and 2,98 g/cm3, 87,3 and 162,1 MPa, respectively, for two types of refractories), reduces open porosity from 20 to 14 %, and also increases the resistance of refractory products (by the duration of their operation) by 25‒35 % compared to the resistance of the base refractory. The use of SiO2 nanoparticle additives reduces the consumption of refractory products and raw materials for their production, and also increases the profitability of production. Ill. 2. Ref. 19.
