Potassium metaphosphates

These neutralization processes may be used for the preparation of various complex fluorides without actually isolating the acid or the base. Thus, for example, if equivalent quantities of metallic silver and gold are dissolved in bromine trifluoride and all volatile material is removed in vacuum, the salt AgAuFg remains. The usefulness of this method is increased by the apparent existence in bromine trifluoride solution of both acids and bases which are not sufficiently stable to be isolated. This is well illustrated by the reaction of potassium metaphosphate with bromine trifluoride, which gives a quantitative yield of KPFg ... [Pg.5]

In the phosphates, partial substitution of oxygen by fluorine also has the effect of reducing the cation anion ratio, e.g. inK2(P03F)2 and K(P02F2) . The first compound is easily obtained by fusion of ELF and potassium metaphosphate... [Pg.141]

Water-insoluble PEC were prepared by mixing oppositely charged polyelectrolytes, e.g. DEAE dextran with CMD [340,341], sodium dextran sulfate, poly(styrene sulfonate) (NaSS) [342], poly(sodium L-glutamate) (PSLG), poly(vinyl alcohol)sulfate [343], or potassium metaphosphate (MPK) [240]. They are useful as membranes or in biomedical applications [343,344]. [Pg.261]

The sodium polyphosphate systems produce glasses very easily while it is difficult to make potassium glasses. The milky glassy masses of potassium metaphosphate compositions obtained by quenching the potassium melts are rich in potassium trimetaphosphate, though the phase diagram for the system contains none. Potassium cyclic triphosphate can be made thermally by dehydrating monopotassium orthophosphate with urea at temperatures less than 300 C,... [Pg.93]

As shown in Ikble 20-2, lithium chloride humidity sensors have rather slow responses to humidity compared to other types of humidity sensors. This type of humitidy sensor cannot, therefore, be used in automatic control systems which require a rapid response. They are, however, widely used for meteorological observations such as radiosonde because of their reproducibility, long term stability, and low cost [7]. Care should be taken when using this type of sensor in very humid environments because the accuracy and lifetime are lowered. Thin films of potassium metaphosphate [9] and barium fluorite [10] are also used as humidity sensors. The film of potassium metaphosphate is deposited on a glass substrate by vacuum sublimation and Ag paste is used as the electrodes. Such sensors show a response to humidity within 2 s, but are not stable [9]. [Pg.287]
