Abstract:
X-ray diffraction analysis and data on the strength and specific surface area are used to study the thermal stability of a
La-Si/Al2O3 system depending on the concentration of introduced additives and calcination temperature. The mechanisms of interactions of these elements and alumina are discussed. Silicon and lanthanum cations begin to interact at low temperatures (∼500°С). The authors assume that silicon and lanthanum cations occupy tetrahedral and octahedral positions, respectively, in the γ-alumina lattice and thus significantly enhance its thermal stability. Up to 50% of γ-Al2O3 is retained at 1200°С, and α-Al2O3 starts to form in the ternary system only at 1300°С.
