Recipe B A solution 0.003 M in SnCl4 and 0.3 M in HCl and 0.3 M in urea was aged for 2 h at 100°C. Properties TEM images, XRD results, IR absorption spectrum, particle size data (depends on solid-to-liquid ratio) available [1954]. 

2 From Alkoxide, Calcined 4.9 moles of water were added drop-wise to a solution of 0.06 mole of Sn(C4H9O)4 in 44 cm of 2-propanol. The dispersion was stirred for 2 h at room temperature and heated for 20 h at 80°C. Then the gel was calcined for 2 h at different temperatures.
