WHAT IS CELESTINE? Celestine or celestite (SrSO4) is a mineral consisting of strontium sulfate. It is very similar to Barite (barium sulfate), but less common Celestine occurs as crystals, and also in compact massive and fibrous forms. It is mostly found in sedimentary rocks, often associated with the minerals gypsum, anhydrite, and halite. Bright yellow sulfur with blue Celestite is one of the most famous colorful combinations of minerals. The ideal composition of Celestite is: SrO 56.42 % SO3 43.58 %


Celestine usages:

  • Celestine is the principal source of the element strontium, commonly used in fireworks and in various metal alloys.
  • Almost all Celestine (99%) is used in the production of strontium carbonate. There are four main uses for Strontium Carbonate. More than 85% of all strontium is consumed in ceramics and glass manufacture, primarily in television faceplate glass and secondarily in ceramic ferrite magnets and other ceramic and glass applications.
