Finally, appropriate dimensionless variables based on a combination of the Fourier, Grashof and Stefan numbers are introduced in order to obtain a generalized correlation for the liquid mass fraction and the Nusselt number during melting of sodium nitrate.
Besides, this molten salt has a reduced cost relative to previous low-melting nitrate mixtures due to the elimination of cesium nitrate and lithium nitrate.
Endo-effect (Fig. 1a, curve 3) in the range of 70 108 °C (maximum at 85 °C) shows melting of the aluminum nitrate nonahydrate with parallel diminution of the sample weight (by 14 wt.% at 140 °C) due to water desorption.
A nearly chromium-free primary spinel formed in the nitrate melt starting from 520°C and eventually dissolved in the borosilicate melt by 1060°C.
It has been found from the measurement of the potential of an oxygen electrode immersed in the melt of an equimolar mixture of KNO3 and NaNO3 that the Cl− anions do not markedly affect this potential, whereas the F−, Br− and I− anions decrease this potential and thus act as Lux bases toward the nitrate melt.
Ammonium nitrate is a colourless, crystalline substance (melting point 169.6° C [337.3° F]).
Both the nitrate 2 and the perchlorate 8 decompose on melting.
Making Smoke Bombs One way melt SIX parts potassium nitrate(saltpeter).
Nitrate salts and metals are used as the PCM core with melting temperatures in the 300-400 °C range.
The activity coefficients of silver nitrate in binary melts of AgNO3-KNO3 were determined by emf measurements in a formation cell consisting of a silver and a nitrate electrode, in a temperature range of 513-583 K and in the concentration range allowed by the melting point of the mixture.
Zinc nitrate hexahydrate (molecular formula, Zn(NO3 2·6H2O; appearance, colorless and deliquescent crystals; molar mass, 297.49 g/mol; density, 2.065 g/cmeltingting point, 36.4°C) was purchased from Hayashi Pure Chemical (Osaka, Japan).
