摘要：

Double layered hydroxides with hydrotalcite structure were synthesized by the sol-gel precess using aluminum and magnesium alkoxides as precursors. The thermal decomposition of sol-gel hydrotalcites was studied by TGA and DTA methods. The sol-gel hydrotalcites show thermal stability up to 550 degrees C.
