coral-building algae, and giant snails engineer their own building material, like magic, by pulling two dissolved chemicals — calcium and carbonate — out of the water to form solid shells of, surprise, calcium carbonate.但是
Light calcium carbonate, also known as precipitated calcium carbonate, is calcined limestone and other raw materials to produce lime (the main component is calcium oxide) and carbon dioxide, and then water is added to digest lime to produce lime milk (the main component is calcium hydroxide), a...
