Solvothermal reactions are designated as the reactions which use high temperatures and/or high pressure solvents. It is possible to control the acid-base reaction rate, morphology and agglomeration of the products, i.e., wel1 dispersed nanoparticles with high crystallinity can be obtained by solvothermal reactions. Therefore, solvothermal reactions are expected to be used to generate environmentally friendly functional ceramic materials. Actually, various functional ceramic materials, such as high performance near infrared shielding materials, UV-shielding materials, automobile exhaust gas cleaning catalysts, etc. have been fabricated by solvothermal reactions.
