摘要
An amorphous powder of titanium oxide and of barium and/or strontium oxide is precipitated by the hydrolysis of titanium alcoholate in the presence of barium oxide, hydroxide or alcoholate or strontium oxide, hydroxide or alcoholate and an acid organic compound containing more than 6 carbon atoms, and the amorphous powder is heated while being treated with a stream of gas containing water vapour, ammonia or CO2, to crystallize the barium or strontium titanate and distill off the acid organic compound. The barium or strontium titanate crystals are less than one micron in size and have an irregular, angular morphology.
