Abstract
The independent crystallization sequence of an Al2O3 component is modified in the presence of SiO2 and vice versa. Mixed SiO2‐Al2O3, gel (28 wt% SiO2 and 72 wt% Al2O3) forms neither cristobalite nor γ‐Al2O3 and corundum at 1000°C but forms Si‐Al spinel; an amorphous aluminosilicate phase invariably also forms after the gel is heated. However, the composition of this amorphous aluminosilicate phase is not as yet known.Keywords
