Alkaline Earth Compounds (Be, Mg, Ca, Sr, Ba)
Alkaline earth compounds have long served as reagents, desiccants, fillers and ceramic raw materials. This sub-category supplies salts and oxides of magnesium, calcium, strontium and barium, along with a small number of beryllium compounds handled under strict controls. Examples include Barium acetate in standard and GR grades, Barium bromide, Barium borate and Barium aluminium oxide powder below 10 µm.
Barium and strontium compounds are important precursors for ferroelectric and magnetic ceramics such as barium titanate and strontium ferrite, where low impurity levels and fine particle size improve sintering. Analytical users choose GR grades for gravimetric sulphate tests and other classical methods. Soluble barium compounds are toxic, so handling and waste rules apply.
- Acetates and halides for synthesis and analysis
- Borates and aluminates for optics and phosphors
- High-purity carbonates and oxides for ceramics
Products ship sealed with a COA and SDS. Toxic barium and strontium salts are declared under dangerous-goods rules where required, and some arsenate and arsenite salts need end-use confirmation.
