Sep 25, 2024 · What is Rochelle Salt? Rochelle salt is a natural salt. Its chemical name is sodium potassium tartrate tetrahydrate. Rochelle salt is also called a double salt of tartaric acid. The first production of the same was done in the year 1675.
Rochelle salt is a potassium-sodium tartratetetrahydrate (KNaC4 H 4 O 6 •4H 2 O) and belongs to the family of uniaxial ferroelectrics. This was the first material in which Valasek discovered the ferroelectric phenomenon in 1921, and from which he also introduced the term Curie temperature or Curie point for ferroelectrics.
