Kalsiyum karbonat
KALSİYUM KARBONAT
Kalsit, kimyasal formülü CaCO3 olan kristalleşmiş kalsiyum karbonat. Saydam, beyaz, sarı, rustik yeşil ve mavimsi renkte olabilir. Sertliği 3, özgül ağırlığı 2.71'dir. Soğuk ve seyreltik hidroklorik asitte (tuz ruhu) şiddetli bir köpürme ile ayrışır. Çakı ile çizilir. CO2'li sularda çözünerek Ca(HCO3)2 yapar.
Nadiren erüptif kayalardan özellikle pegmatitlerde ilksel olarak bulunur. Genellikle sekonder bir mineraldir. Doğada bolca bulunur.Genellikle karbonatlı sedimanter kayaların (ör:kireçtaşları) ve mermerlerin ana bileşenidir. Çeşitli şekillerde işlenerek boya, kâğıt, plastik sektöründe dolgu malzemesi olarak kullanılır. Plastik sektöründe kullanılan kalsitler ise; kaplı ve kapsız olmak üzere 2 çeşittir.
CaCO3 + ısı → CaO (sönmemiş kireç) + CO2
CaO + H2O → Ca(OH)2 (sönmüş kireç)
Türkiye'de Niğde ilinde çıkarılan Kalsit madeni oldukça parlak olmasından dolayı ticari değeri yüksektir
