Solar Thermal Energy Storage Systems
Houses with thermal storage units have been constructed using sodium sulfate, or Glauber's salt. ... It was a 10 MW central power tower system that used a mixture of 60% sodium nitrate and 40% potassium nitrate. This mixture melts at about 220°C and does not decompose until it reaches temperatures greater than 600°C. [11]
Extraction of Copper and Nickel from Low-Grade Nickel
As the sodium sulfate dosage is increased further, the degree of particle adhesion increases and the mass transfer within the system is hindered, which leads to the decrease in the conversion of nickel and copper when x > 0.4. The most favorable sodium sulfate dosage (x) of 0.4 was chosen for the roasting process.

A volume of 800 mL of medium was equilibrated at 37°C for 1 h. Deionized/purified water, 0.1 M phosphate buffer (pH 7.4), and 1% w/v sodium dodecyl sulfate were used as medium for acetaminophen, Na naproxen, and griseofulvin formulations, respectively. Tablets were placed into the basket cylinders, which …
Cobalt and nickel separation in aqueous two-phase systems …
In the system with sodium sulfate (Na 2 SO 4), Ni extraction was suppressed at pH 2, and this enabled efficient Co/Ni separation. • Separation factors of Co to Ni reached 11,080 and 1136 for the aqueous systems with Na 2 SO 4 at pH 2 and pH 1, respectively. • Similar separation factor, as high as 3300, was achieved for the system …

damage from sodium sulfate crystallisation is greater than from other salts remains a subject of continuing debate (Rodriguez-Navarro et al. 2000; Chaterji 2000; Scherer 2000, 2004; Flatt 2002). One reason for this is the complexity of the sodium sulfate system, with two stable phases (thenardite, Na 2SO 4 and mirabilite, Na 2SO 4 10H
