摘要:
By atomizing a siloxane and an organic titanium compound for flame combustion, spherical complex oxide fine particles of amorphous silica-titania are obtained having a particle size of 10-300 nm, a specific surface area of 20-100 m 2 /g, and a titania content of 1-99% by weight. By hydrophobizing the fine particles and adding them to a toner, a developer is obtained which is improved in fluidity, cleanability and uniform and stable charging.
摘要:
Organohalosilane or disilane is subject to pyrogenic hydrolysis in a diffusion flame of hydrogen and air, thereby producing fine particulate silica having a large specific surface area useful as fumed silica.
