HOLLOW PARTICLE WITH SPECIFIC SHELL AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for producing hollow particles for having two or more macropores. <P>SOLUTION: The method for producing the hollow particles having two or more macropores of pore diameter of 60 nm to 30 μm in a part of a shell of silica or alkaline earth metal silicate includes the action of a precipitant aqueous solution on a W/O emulsion obtained by dispersing first aqueous phase particles containing water-soluble silicate and a macropore-forming water-soluble compound in an oil phase. <P>COPYRIGHT: (C)2012,JPO&INPIT |
