Pseudowollastonite is a high-temperature mineral phase of CaSiO3 and is polymorphous with wollastonite. Its formula can alternatively be written as Ca3Si3O9. Other names include ß-Wollastonite, and cyclowollastonite.[3][4]
It occurs in high temperature (pyrometamorphic) environments such as the Hatrurim Formation of the Negev Desert[3] and the graphite mine at Pfaffenrenth near Hauzenberg, Bavaria.[5] It also occurs in slags and cement.
