Knowra Barium carbonate Barium carbonate Barium carbonate (BaCO₃) is an inorganic salt found naturally as the mineral witherite. It is used in ceramics, glassmaking, and other industrial processes.
Barium sulfate : An insoluble barium salt, BaSO₄, used as a radiographic contrast agent and in industrial materials. Unlike barium carbonate, it is extremely insoluble and far less bioavailable.
Ceramic glaze : A glassy coating fused onto ceramic surfaces to add color, texture, or protection. Barium carbonate supplies barium to glazes, affecting their appearance and firing behavior.
Witherite : A rare barium carbonate mineral with composition BaCO₃, named after mineralogist William Withering. It is the naturally occurring mineral form of barium carbonate.
Barium poisoning : Illness caused by exposure to bioavailable barium compounds, which can disrupt muscle and nerve function. Ingested barium carbonate can release toxic barium ions in stomach acid.
Barium chloride : A water-soluble inorganic barium salt, BaCl₂, used in laboratories and industrial processes. Acids can convert carbonate into soluble barium salts such as this one.
Glassmaking : The manufacture of glass by melting silica with additives and shaping the resulting melt. Barium carbonate can provide barium oxide, which modifies glass properties.
William Withering : An English physician and botanist who studied minerals and introduced foxglove into medical practice. Witherite was named in recognition of his mineralogical work.
Barium : A soft, reactive alkaline-earth element with atomic number 56. The compound's biological effects arise from the barium it contains.
Carbon dioxide : A colorless gas, CO₂, produced by respiration, combustion, and carbonate reactions. Acids release this gas when they react with barium carbonate.
Brick manufacturing : The shaping and firing of clay or other mineral materials to produce masonry units. It can be added to brick clays to reduce soluble sulfate defects.
