Application in Chemical Industry
Strontium carbonate is a key ingredient in glazes and used extensively in the ceramics industry. It adds durability and hardness to a glaze and reduces crazing. Coating a substance with strontium carbonate makes it resistant to corrosion, chemicals and the effects of excessive heat. Strontium carbonate-based paints are applied on ships and aircraft fuselages to prevent corrosion.
Application in Pyrotechnics
Strontium carbonate is used extensively in pyrotechnics. Strontium salts burn with a bright red flame and is commonly used as a colorant to impart a bright red flame to fireworks. It is able to effectively neutralize acids in chlorate based firework compositions (which may otherwise ignite spontaneously if trace amounts of an acid are present). Strontium carbonate based pyrotechnics devices are used in both nonmilitary and military applications. Nonmilitary applications include fireworks and warning devices. Military applications that contain strontium carbonate include marine distress signals, military flares and tracer ammunition.
According to the book "Shreve's Chemical Process Industries, " strontium carbonate is used as a screening agent in the plate glass of television picture tubes. Strontium carbonate is used to make strontium ferrite (Sr4Fe4O11). Strontium ferrite magnets are brittle, thick and strong. According to "Industrial Minerals & Rocks: Commodities, Markets, and Uses, " strontium ferrite magnets have high chemical and thermal reactivity, high coercive force and are inert chemically. They are not affected by high temperatures and do not react with chemical solvents. They are resistant to corrosion and can operate optimally between minus 40 Celsius to plus 250 Celsius. Strontium ferrite magnets are used in crafts, toys, loudspeakers, magnetic therapy, novelties, magnetic couplings, holding-magnet systems and electrical motors.
Strontium carbonate is added to molten aluminum to improve its castability and machinability. Strontium carbonate based aluminum is better suitable to make casting items. Cast aluminum is replacing steel in the automotive industry. According to "Industrial Minerals & Rocks: Commodities, Markets, and Uses, " strontium carbonate based cast aluminum improves the fuel efficiency of a vehicle and reduces its weight.
