Strontium Carbonate Powder SrCO3 is Strontium Ferrite Magnetic Materials Application Area
The largest application area of strontium carbonate powder is strontium ferrite magnetic materials
Core application areas of strontium carbonate powder
1. Strontium ferrite
Purpose: To produce strontium ferrite permanent magnets (SrFe ₁₂ O ₁₉), which is one of the most cost-effective permanent magnet materials.
Terminal:
Home appliances: refrigerator/air conditioner compressor motor, washing machine motor, fan, vacuum cleaner, microwave oven magnetron
Automobile: wiper motor, seat adjustment motor, fuel pump, EPS power assist motor, new energy vehicle drive motor (magnetic tile)
Electronics: speaker magnets, magnetic separators, magnetic recorders, sensors, photovoltaic inverters
Industry: Various small motors, power tools, fitness equipment
2. Other strontium salts
As a basic raw material, it produces strontium nitrate, strontium chloride, strontium hydroxide, strontium titanate, etc., which are then used in glass, electronics, ceramics, fireworks, medicine, etc.
3. Metallurgical desulfurization
High temperature desulfurizer is used in steel smelting to generate SrS with sulfur, reducing the sulfur content in steel and improving its toughness and cleanliness.
Also used as an alloy additive to improve corrosion resistance and mechanical properties.
4. Electronic components
High purity electronic grade strontium carbonate:
Manufacturing PTC thermistors (demagnetization, starting, current limiting, constant temperature)
Production of strontium titanate (SrTiO ∝) for use in piezoelectric ceramics, resonators, filters, MLCC (multilayer ceramic capacitors)
High end glass substrates, optical glass, LED phosphors, semiconductor packaging materials
5. Fireworks/signals
Burning produces bright red flames, used for fireworks, signal flares, warning lights, and fluorescent glass.
6. Ceramics and Glass
Ceramics: Glaze assisted melting/modification to enhance the gloss, strength, and thermal shock resistance of tiles/sanitary ware; Ceramic raw materials for capacitors.
Glass:
Traditional: Color TV CRT glass shell (absorbs X-rays)
Modern: Optical glass, LCD glass, automotive glass, packaging glass (increased refractive index, light transmission, UV resistance)
Application demand trend of strontium carbonate powder
Magnetic materials (strontium ferrite): Benefiting from the growth of new energy vehicles, household appliances, industrial motors, and photovoltaics, with stable demand, they are the main growth engine for strontium carbonate.
Electronic grade strontium carbonate: 5G, MLCC, semiconductors, and high-end displays are driving a rapid increase in demand for high-purity products with higher added value.
The demand in metallurgy, fireworks, glass and other fields is relatively stable.
