Kubera ko calcium ifitanye isano ikomeye na ogisijeni, sulfure, hydrogène, azote na karubone mu byuma byashongeshejwe, amavuta ya silicon-calcium akoreshwa cyane cyane mu kwangiza, gutesha agaciro no gutunganya sulfuru mu byuma bishongeshejwe.Kalisiyumu silicon itanga ingaruka zikomeye iyo yongewe kumashanyarazi.Kalisiyumu ihinduka imyuka ya calcium mu byuma bishongeshejwe, bigira ingaruka zikomeye ku byuma bishongeshejwe kandi bigira umumaro wo kureremba bitarimo ubutare.
