The preparation process of the fused salt is simple, the working temperature range is wide, and the volatilization of components is reduced under long-time operation, so the fused salt is an excellent low-melting-point mixed fused salt heat storage and heat transfer material.徐芳...

As one of the β phase stabilizers, Nb element has the lower melting point (2477 °C) and less melting absorption energy than both Ta and Mo elements, endowing Ti-Nb alloys a better workability [4,5]. On the other hand, the excellent ductility of Ti-Nb alloys prevents the initiation ...
Physical constants for more than 280 common inorganic compounds. Density is given for the actual state at 25°C and for liquid phase at melting point temperature.
Reaction: 1) 1st EQP: H2SO4 + Na2C03 → NaHCO3 + NaHSO4 2) Heating 3) 2nd EQP NaHCO3 + NaHSO4 →H2O + CO2 + Na2SO4 It is observed that for higher concentration without heating the solution after the first equivalence point, carbon dioxide was evolved and second equivalence point ...
In the SLM process, the maximum temperature in the center of the molten pool can reach 2200°C, which is much higher than the melting point of 892°C of the alloy system (Zr55Cu30Ni5Al10). Note that the critical cooling rate required to form the amorphous phase in the Zr55Cu30Ni5...
