摘要:
A method of making cermet inert anodes for the electrolytic production of metals such as aluminum is disclosed. The method includes the step of spray drying a slurry comprising ceramic phase particles and metal phase particles. The resultant spray dried powder, which comprises agglomerates of both the ceramic phase and metal phase particles, may then be consolidated by techniques such as pressing and sintering to produce a cermet inert anode material. The ceramic phase may comprise oxides of Ni, Fe and at least one additional metal selected from Zn, Co, Al, Li, Cu, Ti, V, Cr, Zr, Nb, Ta, W, Mo, Hf and rare earths. The metal phase may comprise Cu, Ag, Pd, Pt, Au, Rh, Ru, Ir and/or Os. The consolidated cermet inert anode material exhibits improved properties such as reduced porosity. The cermet inert anodes may be used in electrolytic reduction cells for the production of commercial purity aluminum as well as other metals.

A fluid bed spray process is described where one or more carbohydrates are incorporated into an echinocandin formulation to provide a significant improvement in thermal stability. The carbohydrate is solubilized with an echinocandin compound or echinocandin/carbohydrate complex in a solvent(s) to form a pharmaceutical solution which is sprayed onto the surface of a granular diluent or carrier. Alternatively, a granulating agent is added to the pharmaceutical solution which is then sprayed onto the surface of a non-granular diluent or carrier. The resulting granular oral formulations and medicaments derived therefrom are also described.

The invention relates to a process for the manufacture of a pharmaceutical composition with modified release of active principle comprising at least one active principle, a lipid matrix agent composed of ester of alcohol with at least one fatty acid and at least one adjuvant. This process is characterized in that: a powder composed of at least one component selected in the group comprising the active principle and the adjuvant, is mixed, while heating and fluidizing, in order to obtain individual grains; the said lipid matrix agent is liquefied separately under warm conditions; the said powder is then coated under warm conditions by spraying the said lipid matrix agent over the individual grains; finally, the temperature of the combined product is lowered in order to allow the lipid matrix agent to solidify.
