Caustic Treatment of Zircon in the Preparation of Pure Zirconium Compounds

From abstract: This investigation was conducted in order to develop a process whereby the most abundant zirconium ore, namely zircon, could economically be put into solution and purified adequately for use in hafnium separation processes employing liquid-liquid extraction. Secondary aims concerned the preparation of pure zirconyl chloride, zirconyl nitrate, zirconyl sulfate, and zirconium oxide from the zircon ore.

Experimental investigation of physical and combustion properties of several residual fuel oils and magnesium - fuel-oil slurries in a ram-jet-type combustor (open access)

Experimental investigation of physical and combustion properties of several residual fuel oils and magnesium - fuel-oil slurries in a ram-jet-type combustor

Report presenting an experimental investigation using a 1 7/8-inch diameter burner to determine the suitability of residual fuel oils as carriers in magnesium slurries. Four residual fuel oils with varying viscosities were investigated by themselves and in slurries of 50 percent magnesium. Results regarding the settling characteristics, blow-out velocity, and combustion efficiency are provided.

Internal performance characteristics of variable-throat plug- and vaned-type convergent-divergent nozzles (open access)

Internal performance characteristics of variable-throat plug- and vaned-type convergent-divergent nozzles

Investigation of the internal performance characteristics of three types of variable-throat convergent-divergent nozzles over a wide range of pressure ratios. Only small differences in peak thrust coefficient between the three types of variable-throat convergent-divergent nozzles were obtained.

Possible Process Alternatives for Converting Recovered Uranyl Nitrate to Uranium Hexafluoride (open access)

Possible Process Alternatives for Converting Recovered Uranyl Nitrate to Uranium Hexafluoride

The uranium recovery processes which are in operation or under construction at the present time--TBP, Redox and Purex--yield an aqueous uranyl nitrate solution as the recovered uranium product. For conversion of this recovered uranium to UF6 for feed to the gaseous diffusion plants, the uranyl nitrate in the solution is concentrated with or without prior organic stripping, calcined to UC3, reduced to UO2 with hydrogen, hydro-fluorinated to UF4 with RF, and finally fluorinated to UF6 with elemental fluorine.
