Abstract: 
Суперкислотні потрійні ZrO2 SiO2 SnO2 оксиди (Н0 = –14.52) синтезовано золь-гель методом з атомним співвідношенням в межах: 20 ≤ Zr4+ ≤ 29, 60 ≤ Si4+ ≤ 67, 11 ≤ Sn4+ ≤ 20 %. Суперкислотність ZrO2 SiO2 SnO2 оксиду пояснена формуванням координаційно-ненасичених Zr4+ йонів, як сильних центрів Льюїса
