According to this method, the antibiotic powder is uniformly dispersed in various dispersing mediums and antibiotic products having high antibiotic action is effectively be provided by using the resulting dispersion.Field of SearchComposition having ingredient providing biocidal or biostatic protection thereto or process of preparingProcess of forming a composition having a nonreactant material selected for its special void characteristic; or composition containing same, e.g., syntactic foam, etc. Removing material at reduced pressure, e.g., flashing, sublimation, spray drying, etc. Membrane or process of preparing Metal atom other than aluminum, e.g., zeolites, etc. | |
