Crystal structure of calcite

kailsiym kaarbonet (Calcium carbonate) ek raasaayanik yaugik hai jiska raasaayanik sootr CaCO3 hai. yeh sansaar ke sabhi bhaagon ki shailon mein paaya jaane wala aam padaarth hai. samudri jantuon (ghongha, CP, kolabaal aadi) ke kavachon (shells) ka yeh pramukh avayav hai. yeh krushi choone ka sakriya ghatak hai. chikitsa ke kshetr mein yeh kailsiym ki kami ko door karne ke liye tatha amlarodhi (antacid) ke roop mein prayukt hota hai.
