Ammonium nitrates, solid-phase transitions

Table 1.4 presents the melting heats of polymers and polymer-composite materials at temperatures of solid-phase transitions of nitric salts, coinciding with sevilene fluidity temperature of 80°C. According to [4], ammonium nitrates have sohd-phase transitions at temperatures of SO C and 130°C with AH equal to 0.32 eeal/mol and 1.01 ceal/mol, respectively the salt KNO has the solid-phase transition at 130°C with AH equal to 1.3 ccal/mol. [Pg.10]

Table 1 summarizes the range of catalysts, as well as conditions for the conversion of hexagonal to cubic BN. Catalysts that react with hexagonal BN to form ammonium borate, such as H2O, urea, ammonium nitrate, ammonium sulfate, and boric acid are potentialy effective in tests with up to 40 wt % of catalyst . Pyrophyllite is used as a solid pressure medium, and known phase transitions of Bi, Tl, and Ba serve to calibrate the pressure. [Pg.317]
