A process for the preparation of granular fertilizer grade DAP (a product composed of ammonium phosphates, principally diammonium phosphate, resulting from the ammoniation of phosphoric acid, as defined in Official Publication No. 52 of the Association of American Plant Food Officials, dated 1999) comprising partially preneutralizing orthophosphoric acid with ammonia, completing the ammoniation of the orthophosphoric acid with ammonia in a rotary ammoniator-granulator to provide granular DAP, sizing the granular DAP to provide the granular DAP product, reducing the particle size of the oversized granular DAP, and recycling the undersized granular DAP and the sized-reduced oversized granular DAP to the ammoniator-granulator. The ammoniacal nitrogen concentration of the granular DAP recycle, hence the granular DAP product, is enhanced by subjecting the finely-divided recycled granular DAP to anhydrous gaseous ammonia which is at a super atmospheric pressure and which is at a temperature sufficient to maintain said anhydrous ammonia in the gaseous state. The increase in the ammoniacal nitrogen concentration is a function of the absolute ammonia pressure, the initial moisture content of the granular DAP recycle, and the contact time of the ammonium with the granular DAP recycle.

A method for preparing nanocrystalline ceramic thin films, particularly at low firing temperatures <1000° C. The method for preparing ceramic thin films comprises preparing a seed gel of metal oxide, dissolving a source compound for cations of the oxide's metal constituents in the solution, then adding a polymerizable organic solvent to the solution and heating to form a polymeric precursor having uniformly dispersed gel seeds within a solid gel structure whereby any voids within the structure are filled with metal cation-containing polymeric precursor. The polymeric precursor is free of precipitates. A surface of a substrate is then coated with at least one layer of the gel-seeded polymeric precursor to form a uniform film of gel-seeded polymeric precursor wherein the film has a thickness of 100 nm to 200 nm per layer. The film is then sintered to convert the film to a nanocrystalline ceramic thin film having a thickness of 100 nm to 1 mum and being substantially free of defects.
