2013-4-1  Sodium sulfate is recognized as a salt with probably the most damaging capabilities when crystallizing in porous media. The three main crystalline phases which can be formed are thenardite (Na 2 SO 4, anhydrous salt), decahydrate (Na 2 SO 4 10H 2 O) and the thermodynamically metastable heptahydrate (Na 2 SO 4 7H 2 O). In this study, using a setup in which nuclear magnetic resonance

Sodium Sulphate - Homepage Tradeasia International Pte

Sodium sulfate anhydrous, also known as thenardite, has a formula of Na2SO4. It has an appearance of white crystalline solid and is chemically very stable. It is unreactive toward most oxidizing or reducing agents at normal temperatures. In addition to that, it can be converted to sodium sulfide at high temperature by carbo-thermal reduction.
