Glass Refractory : u/ricehusk
Glass defects occur in many different forms while the defect sources exhibit a consider. The glass furnace refractories have to go through severe environmental conditions throughout the process. Their selection is vital for the quality of the glass and the length of process. Thermal shock, physical wear, high temperature and corrosive chemicals affects the refractory and hence the furnace performance. They are materials that can resist high temperatures and are expected to maintain …

Boundary Layers Refractory/Glass Melt and Glass …
The reaction between refractories and glass melts is determined by the diffusion of the different ions from the glass melt into the refractory material and vice versa. The connected solution reactions lead to the formation of a saturation boundary layer, which influences the corrosion behaviour and the glass defect potential.
