IPC: B01J21/10
Filed: 1995-04-07
Abstract: PURPOSE: To arbitrarily control the size of a fine space formed of an air gap of fillers and to reduce the irregularity by charging mixture of annlar white filler and polymer binder in a column, baking it at the baking temperature of the binder and altering the primary grain size of the filler. CONSTITUTION: When mixture of granular white filler and rubberlike polymer binder having different grain sizes is charged in a column, the temperature is raised, for example to 400 deg.C lower by 50 deg.C than the decomposing temperature of the binder in three hours, held for one hour to suppress the abrupt decomposition of the binder to prevent the formation of irregularly fine space, and the mixture is then baked at about 600 deg.C for 2 to 6 hours, fine space of about several nm to several tens nm is formed in the filler in response to the grain size. Accordingly, according to this method, the size of the fine space formed by the air gap between the fillers can be arbitrarily controlled in the order of several nm to several tens nm, and further since the mixture has a plenty of fluidity, it can be charged without restricting in the size and the shape of the column.
