Application

Strontium carbonate is a versatile compound with a variety of applications due to its unique properties. It is mainly used in the manufacturing of radiation-resistant glass and TV picture tubes, which benefit from its ability to coat the glass in cathode-ray screens. Additionally, strontium carbonate is employed in the field of pyrotechnics, where it provides a stunning red flame effect in fireworks. The compound is also utilized as a slagging agent in certain metal furnaces and plays a role in the refining of sugar. Naturally found as the mineral strontianite, strontium carbonate's occurrence in white or slightly gray orthorhombic crystal forms adds to its appeal. Its resilience and specific heat decomposition point make it suitable for various industrial applications, highlighting its importance across multiple sectors.
