Description

Strontium Sulfate CAS NO 7759-02-6 is an inorganic salt of strontium and sulfuric acid, known for its high density and chemical inertness. This compound is valued for its ability to provide opacity and density in various industrial formulations. It serves as a critical functional additive in sectors such as ceramics, pigments, and specialty glass manufacturing, where its specific gravity and stability are essential.

Application

• Ceramics & Glass Manufacturing: Used as a flux and opacifier to modify melting points and enhance the brilliance and opacity of glazes, enamels, and specialty glasses.
• Pigments & Fillers: Acts as an inert, high-density filler and extender in paints, coatings, and plastics to improve weight, texture, and chemical resistance.
• Pyrotechnics & Signaling Flares: A key component for producing intense red-colored flames in fireworks and emergency signal devices.
• Electronics: Utilized in the production of certain ferrite magnets and other electronic ceramics.
• Drilling Fluids: Serves as a high-density weighting agent in oil and gas drilling muds to control wellbore pressure.
• Analytical Chemistry: Employed as a standard or reagent in specific laboratory analyses and quality control procedures.
