Figure 1From: Specific heat capacity of molten salt-based alumina nanofluidNanofluid synthesis. (a) A mixture of molten salt powder and alumina nanoparticles was prepared in a beaker; (b) The same weight of DI water was added into the beaker; (c) The solution was mixed up in an ultrasonic for 100 min; (d) The DI water was evaporated via heating the solution on a hot plate at 90°C for 12 h; (e) The solution was melted at 300°C in a high-temperature oven.Back to article page
