TITANIUM OXIDE PARTICLES, PROCESS FOR PRODUCING SAME, MAGNETIC MEMORY, OPTICAL INFORMATION RECORDING MEDIUM, AND CHARGE ACCUMULATION TYPE MEMORY |
摘要 |
A titanium oxide particle that can develop non-conventional and novel physical properties, a method for manufacturing the same, and a magnetic memory, an optical information recording medium, and a charge accumulation type memory using the same are provided. A silica-coated titanium hydroxide compound particle is directly produced through a sol-gel technique and not through a reverse micelle technique, and the silica-coated titanium hydroxide compound particle is subjected to a calcination process. Hence, a titanium oxide particle 1 can be provided which can develop non-conventional and novel physical properties such that it does not perform phase transition at a room temperature and a Ti 3 O 5 particle body can always maintain the characteristic as a paramagnetic metal in all temperature ranges unlike conventional bulk bodies that perform phase transition between a non-magnetic semiconductor and a paramagnetic metal at a temperature near about 460 K. |
