  • Patent number: 8025725
    Abstract: According to the present invention, there is provided a temperature-sensitive aluminum phosphate solution, characterized in that, composition of the aluminum phosphate is within such ranges that 3Al2O3/P2O5 (molar ratio) is from 1.2 to 1.5, M2O/P2O5 (molar ratio) (M is an alkali metal) is from 0.02 to 0.15 and concentration of Al2O3 is from 2 to 8% by mass and the sensing temperature is within a temperature range of from 20 to 100° C. The solution is particularly useful as an antioxidant for carbon materials.
