To study the influence of solution concentration on forming precursor in synthesis large quantities of imogolite, the products were synthesized from the precursor formed from the solution of several concentrations. Imogolite were synthesized from the precursor formed from any concentration of solution, the concentration of solution on forming precursor did not influence the formation on imogolite in synthesis large quantities of imogolite. The precursor of imogolite was amorphous from the data of X-ray diffraction pattern, and the infrared spectrum of precursor was almost same as that of allophane. On the other hand, water vapor adsorption isotherms of precursor possess a sharp increase in adsorption when the relative humidity is at 0-10%. The differential thermal analysis curve of the precursor possess a endothermic peak at 360-400°C. So the precursor had a part of imogolite structure or imogolite-like structure.
