TEMPERATURE-SENSITIVE ALUMINUM PHOSPHATE SOLUTION, METHOD FOR PRODUCTION THEREOF, AND USE THEREOF

摘要

Disclosed is a temperature-sensitive aluminum phosphate solution having a 3Al<SUB>2</SUB>O<SUB>3</SUB>/P<SUB>2</SUB>O<SUB>5</SUB> ratio (by mole) ranging from 1.2 to 1.5, a M<SUB>2</SUB>O/P<SUB>2</SUB>O<SUB>5</SUB> ratio (by mole)ranging from 0.02 to 1.15 (wherein M represents an alkali metal) and a Al<SUB>2</SUB>O<SUB>3</SUB> content ranging from 2 to 8 mass%, which is characterized by having a sensing temperature lying within the range from 20 to 100°C. The solution is particularly useful as an antioxidant agent for a carbon material.
