摘要:Methods of controlling crystal polymorphism in organic-free synthesis of Na-Zeolites and the zeolite crystals formed using those methods are provided. The methods disclosed herein create certain types of zeolite crystals more efficiently than other previously known methods. The methods also create certain types of zeolite crystals in a form and concentration not previously disclosed. The methods disclosed herein generally comprise using solutions with varying ratios of silicon (Si), aluminum (Al), hydroxide (OH), and water. Some implementations of the invention disclosed include efficient methods of producing nearly pure cancrinite (CAN), methods of obtaining sodalite in solutions with a high Si/Al ratio, and a method of forming thin, platelet-like ANA crystals with a width of less than about 1 μm and a length of at least about 3 μm.

摘要:In a method of synthesizing a silicoaluminophosphate molecular sieve having 90%+ CHA framework type character, a reaction mixture is prepared comprising first combining a reactive source of aluminum with a reactive source of phosphorus to form a primary mixture that is aged. A reactive source of silicon and a template for directing the formation of the molecular sieve can then be added to form a synthesis mixture. Crystallization is then induced in the synthesis mixture. Advantageously, (i) the source of silicon comprises an organosilicate, (ii) the source of phosphorus optionally comprises an organophosphate, and (iii) the crystallized silicoaluminophosphate molecular sieve has a crystal size distribution such that its average crystal size is not greater than 5 μm. The molecular sieve can then preferably be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

摘要:In a method of synthesizing a mostly CHA-type silicoaluminophosphate sieve, a reaction mixture comprises sources of water, silicon, aluminum, phosphorus, and a template. In one aspect, the inorganic phosphorus and silicon sources are first combined to form a primary mixture that is aged. Then, the aluminum source is added, followed optionally by any organic phosphorus source, and then the template, to form the synthesis mixture. After heating at <10°C/hr to induce crystallization, in this aspect, both the crystallized sieve has an average crystal size ≤1.5μm and/or is recovered in a yield of ≥10.0wt%. In another aspect, when the synthesis mixture Si/Al2 ratio is <0.33, crystallization is induced. Advantageously, the sieve so crystallized has a template efficiency of ≥0.5 and/or is recovered in a yield of ≥10.0wt%. The molecular sieve from both aspects can be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

摘要:Nanocomposite thin films with low dielectric constants are made by the simultaneous deposition of an oxide dielectric and an organic polymer at near room temperatures. Suitable oxides include SiO 2 , and suitable organic polymers include poly(chloro-para-xylylene). The two dielectric materials, when deposited, form nanocomposites characterized by nanometer-sized domains of dielectric material. The nanocomposite thin films of this invention are useful as dielectric layers for interlevel dielectric (ILD) and intermetal dielectric (IMD) dielectrics in the manufacture of semiconductor devices as well as for thin films for flat panel displays, food wraps, hybrid ceramics, glass, hard disk drives, and optical disk drives. Additionally, the invention comprises semiconductor devices and semiconductor chips made incorporating nanocomposites deposited by chemical vapor deposition.

摘要:In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.
