Potassium carbonate nitrate

Contact of powdered titanium with molten potassium chlorate, alkali-metal carbonates or mixed potassium carbonate/nitrate causes vivid incandescence. 

The catalyst components are mixtures of oxides which have been fused in an electric arc furnace at temperatures of ca 2000 K. The resulting large blocks of black hard material are broken into lumps of usually ca 1 cm diameter. The visual homogeneity of these lumps is, in general, a good indicator for the quality of the final activated catalyst. Poor catalysts exhibit white spots of segregated promoter oxides and bubble holes caused by evaporation of impurities during the fusion process. Primary sources of iron can be iron ores, scrap metal, or iron oxides (oxyhydrates) from other industrial processes. Potassium is added as potassium carbonate, nitrate, or potassium hydroxide, aluminum as alumina and calcium as oxide or carbonate. 

Ion-selective electrodes are available for the electro analysis of most small anions, eg, haUdes, sulfide, carbonate, nitrate, etc, and cations, eg, lithium, sodium, potassium, hydrogen, magnesium, calcium, etc, but having varying degrees of selectivity. The most successful uses of these electrodes involve process monitoring, eg, for pH, where precision beyond the unstable reference electrode s abiUty to deUver is not generally required, and for clinical apphcations, eg, sodium, potassium, chloride, and carbonate in blood, urine, and semm. 

A 500-ml flask is equipped with a condenser and a magnetic stirrer and charged with 175 ml of water, 18 ml ofTHF, lOg of potassium carbonate, 6.5 g of silver nitrate, and 10 g of 1-bromoadamantane. The mixture is heated in a boiling water bath for 1 hour with stirring, cooled, and the crystallized 1-adamantanol is collected by filtration. It may be purified by dissolving it in THF and diluting the solution with water. The product has mp 289-290°. 

Molten salt extraction residues are processed to recover plutonium by an aqueous precipitation process. The residues are dissolved in dilute HC1, the actinides are precipitated with potassium carbonate, and the precipitate redissolved in nitric acid (7M) to convert from a chloride to a nitrate system. The plutonium is then recovered from the 7M HNO3 by anion exchange and the effluent sent to waste or americium recovery. We are studying actinide (III) carbonate chemistry and looking at new...

Zirconium reduces almost all oxygen-containing salts. This is the case for alkali hydroxides (accidents with the lithium, sodium and potassium compounds) and zirconium hydroxide, lithium, sodium and potassium carbonates, alkaline sulphates sodium tetraborate and copper (II) oxide. This is true especially for oxidising salts such as alkaline chromates and dichromates, chlorates (accident with potassium salt) and nitrates (accident with potassium salt). 

Potash (composed of potassium oxide), also a flux, was mainly used as a glass modifier. It was generally introduced into the glass melt in the form of either pearl ash, composed of potassium carbonate, vegetable ash, one of the main constituents of which is potassium carbonate, or saltpeter, a mineral composed of potassium nitrate. 

Analytical decomposition of powdered diamond by fusion with potassium hydroxide may become explosive. This can be avoided by fusion with a potassium carbonate-sodium carbonate mixture, followed by addition of small portions of potassium nitrite or nitrate. 

Red phosphorus, sulfur but with carbon, the observed ignition has been attributed to presence of impurities mercury iodide, potassium iodide, silver nitrate, potassium carbonate.

Perhaps the most unusual modern application of potassium nitrate-based powders is in the fire protection industry. The white smoke mainly consists of potassium carbonate and this has been found to have fire extinguishing properties due to the way in which the potassium salt in the smoke interferes with the combustion chemistry of a fire. 

The industrial term potash can be very misleading. It can refer to potassium carbonate (K2CO3), potassium hydroxide (KOH), potassium chloride (KCl), potassium sulfate (K2SO4), potassium nitrate (KNO3), or collectively to all potassium salts and to the oxide K2O. More correctly KOH is called caustic potash and KCl is called muriate of potash. Production is recorded in weight equivalents of K2O since almost all potash is used as fertilizer and this industry quotes weight percentages of K2O in its trade. 

Tungsten metal is not affected by aqueous alkalies at room temperature. In molten state, caustic soda and caustic potash slowly oxidize tungsten in the presence of air. Oxidiation is more rapid in the presence of an oxidizing agent such as potassium nitrate, potassium chlorate, or lead dioxide. A similar reaction occurs with fused sodium or potassium carbonate. Tungsten dissolves...

Plumes from biomass burning can also have unique signatures. For example, organics, ammonium, potassium, sodium, nitrate, nitrite, sulfate, chloride, phosphate, elemental carbon, and the anions of organic acids (formate, acetate, oxalate, etc.) have all been measured in particles in the plumes from burning vegetation (e.g., see Cofer et al., 1988 Andreae et al., 1988 and Artaxo et al., 1994).

The chlorides, bromides, iodides, and cyanides are generally vigorously attacked by fluorine in the cold sulphides, nitrides, and phosphides are attacked in the cold or may be when warmed a little the oxides of the alkalies and alkaline earths are vigorously attacked with incandescence the other oxides usually require to be warmed. The sulphates usually require warming the nitrates generally resist attack even when warmed. The phosphates are more easily attacked than the sulphates. The carbonates of sodium, lithium, calcium, and lead are decomposed at ordinary temp, with incandescence, but potassium carbonate is not decomposed even at a dull red heat. Fluorine does not act on sodium bofate. Most of these reactions have been qualitatively studied by H. Moissan,15 and described in his monograph, Lefluor et ses composes (Paris, 1900). 

The world s consumption of sodium nitrate in 1912 was 2,460,000 tons and in 1914, 2,633,000 tons. Sodium nitrate can be converted into potassium nitrate by double decomposition with potassium chloride,7 with potassium hydroxide 8 or with potassium carbonate and also by first converting it into barium nitrate and...
