COMPOSITION FOR DISPERSING OF PARTICLE, COMPOSITION HAVING PARTICLE DISPERSED THEREIN, PROCESS FOR PRODUCING THE SAME, AND SINTERED COMPACT OF ANATASE TITANIUM OXIDE

摘要

[PROBLEMS] To provide a composition for dispersing of particles that exhibits excellent dispersing effects as to various particle suspensions and avoids any impact on environment; to provide a composition having particles stably dispersed therein and a process for producing the same; and to provide a sintered compact of anatase titanium oxide. [MEANS FOR SOLVING PROBLEMS] There is provided a composition for dispersing of particles, characterized by being obtained by mixing together a metal alkoxide containing a metal element of +3 to 5 valence (for example, titanium or the like), an organic acid (for example, lactic acid or the like) and water. Further, there is provided a composition having particles dispersed therein, characterized by containing particles (for example, oxide particles or the like) and the above composition for dispersing of particles. Still further, there is provided a process for producing the composition having particles dispersed therein, characterized by including the mixing step of mixing together the composition for dispersing of particles, particles and a solvent (for example, water or the like) wherein the amount of composition mixed is controlled depending on the isoelectric point of the particles.
