Organic-inorganic composition for the vapour release of alkali or alkali-earth metals

摘要

A composition of precursors for the release of vapors of alkali or alkali-earth metals is described. The composition has at least a compound of alkali or alkali-earth metal, at least a reducing agent and optionally an absorbing material, all in the form of powders, dispersed in a viscous matrix of hybrid organic-inorganic type. Dispensers for the release of these metals obtained through the composition and micro-electronic devices are also described.

1. A composition containing precursors comprising at least a compound of alkali or alkali-earth metal, and at least a reducing agent,
said compound and said reducing agent being dispersed in the form of powders within a hybrid organic-inorganic binder, said binder comprising at least an organic thickener component and at least an inorganic stabilizer component, wherein said precursors are suitable for the release of alkali or alkali-earth metals and said compound of alkali or alkali-earth metal is selected among zirconates, silicates, tantalates, niobates, tungstates, molybdates and titanates of alkali or alkali-earth metals, wherein the viscosity of said composition is between 50 cP and 5000 cP.
