The N methodology may allow for fumed metallic oxide particles, such as fumed silica and fumed alumina particles, to be processed into a C:N globular morphology to improve handling while retaining a desirable surface area. The processes may include providing fumed metallic 1-1 ---- oxide particles, combining the particles with a liquid carrier to form a suspension, atomizing the solution of suspended particles, and IN subjecting the atomized droplets to a temperature range sufficient to remove the liquid carrier from the droplets, to produce metallic © oxide-containing agglomerations. ei C [Continued on next page] WO 2017/192372 Al MIDEDIMOMOIDEIROIDEMOMMEIMIDEIHHIMEHOIMIE (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
