There is a substantial production of defluorinated phosphate rock for fertilizer usage in Japan (about 100,000 tpy). Ground, high-grade rock is mixed with small proportions of sodium carbonate or sulfate and wet-process acid. The mixture is calcined at a temperature of ISSO C in an oil-fired rotary kiln 45.0 m in length and 2.7 m in diameter. The product contains 38%-42% P2O5 of which more than 90% is soluble in neutral ammonium citrate solution. Substantially all of the fluorine is driven off. Sodium bifluoride (NaHp2) is recovered as a byproduct. A similar product is made in the United States, but it is mainly used for animal feed supplement. The principal phosphate compound in the product is tricalcium phosphate. 

Details of the TIBC assay differ slightly from assay to assay. Typically, 1 mL of serum is mixed with 0.1 mL ferric ammonium citrate (1.25 mmol Fe /liter) for 10 min after which 2 mL barbital-NaCl buffer and 0.4-0.5 g of magnesium carbonate (light powder) are added. Mix for 15 min on a rotary mixer after capping with parafilm. Centrifuge for 10 min at ISOOxg remove 2 mL of the supernatant solution, and spectrophotometrically analyze for iron as described above. Correction for the serum dilution (3 1) is included in calculating the TIBC.

OC-Hydroxycarboxylic Acid Complexes. Water-soluble titanium lactate complexes can be prepared by reactions of an aqueous solution of a titanium salt, such as TiCl, titanyl sulfate, or titanyl nitrate, with calcium, strontium, or barium lactate. The insoluble metal sulfate is filtered off and the filtrate neutralized using an alkaline metal hydroxide or carbonate, ammonium hydroxide, amine, or alkanolamine (78,79). Similar solutions of titanium lactate, malate, tartrate, and citrate can be produced by hydrolyzation of titanium salts, such as TiCl, in strongly (>pH 10) alkaline water isolation of the... 

The clear solution, obtained by centrifuging a solution of the oxide in aqueous ammonia which had been treated with silver nitrate until precipitation started, exploded on two occasions after 10-14 days storage in closed bottles in the dark. This was ascribed to slow precipitation of amorphous silver imide, which is very explosive even when wet [1], When silver oxide is dissolved in ammonia solution, an extremely explosive precipitate (probably Ag3N4) will separate. The explosive behaviour is completely inhibited by presence of colloids or ammonium salts (acetate, carbonate, citrate or oxalate). Substitution of methylamine for ammonia does not give explosive materials [2],... 

Lea produced his allotropic silver (4) by treating in the cold 200 cc. of a 10 per cent silver nitrate solution with a mixture consisting of 200 cc. of 30 per cent ferrous sulfate, 250 cc. of a 40 per cent sodium citrate solution, and 50 cc. of a 10 per cent sodium carbonate solution. The violet precipitate was filtered and washed in water. In order to remove the impurities the precipitation was repeated a number of times with ammonium nitrate. Finally the solution was evaporated and a mass with a metallic luster obtained that consisted mostly of silver. Lea found that the metal did not diffuse through membranes and that it could be freed by this means from electrolytes. Because of these properties and also because inorganic colloids were considered to be allotropic modifications of the metals in question, Lea decided that his silver must also be an allotropic form. Even today we are not in a position to deny this assertion. Barus and Schneider f have shown that it is not at all necessary to assume allotropic modifications in order to explain the subdivision in water or the behavior of the colloid toward electrolytes. We have therefore no direct evidence that the metal in the colloidal state is not an allotropic modification but the assumption is quite unnecessary and perhaps improbable. On the other hand recent work has shown that allotropy is not so uncommon as it was previously supposed, and if the rule proposed by W. Oswald holds, that the more unstable form appears first, it may very well be that colloidal metals contain, or are, allotropic modifications.
