Hoʻomaʻemaʻe i ka hao i hoʻoheheʻe ʻia i nā mea hoʻoheheʻe ʻia i nā mea hoʻohui mea hoʻohui mea kūʻai aku i nā mea kūʻai aku.

ʻO kahi alloy binary i haku ʻia me ke silika a me ka calcium no ka ʻāpana o nā ferroalloys. ʻO kāna mau mea nui he silikoni a me ka calcium, a loaʻa pū kekahi i nā haumia e like me ka hao, aluminika, kalapona, sulfur a me ka phosphorus ma nā ʻano like ʻole. I ka hao a me ka ʻoihana kila, hoʻohana ʻia ia e like me ka mea hoʻohui calcium, deoxidizer, desulfurizer a me denaturant no nā mea hoʻohui ʻole. Hoʻohana ʻia ia ma ke ʻano he inoculant a denaturant i ka ʻoihana hao. Ma ke kumu o ka silicon-calcium alloy, ua hoʻohui ʻia nā mea ʻē aʻe e hana i ka ternary a i ʻole multi-element composite alloy. E like me Si-Ca-Al; Si-Ca-Mn; ʻO Si-Ca-Ba, a me nā mea'ē aʻe, hoʻohanaʻia e like me deoxidizer, desulfurizer, denitrification agent a me ka mea hoʻohui i ka hao a me ke kila kila.

ʻO ka calcium kahi metala honua alkaline me ke kaumaha atomika o 40.08, he hale uila waho o 4S2, he mānoanoa (20°C) o 1.55g/cm3, kahi hehee o 839±2°C, a me kahi paila o 1484° C. ʻO ka pilina ma waena o ke kaomi mahu o ka calcium a me ka mahana

lnpCa=25.7691-20283.9T-1-1.0216lnT

Ina pCa ke kaomi mahu o ka calcium, Pa; ʻO T ka wela, K. Silicon a me ka calcium i ʻekolu mau pūhui, ʻo ia hoʻi ʻo CaSi, Ca2Si a me CaSi2. Paʻa ʻo CaSi (41.2% Si) i nā wela kiʻekiʻe. ʻO Ca2Si (29.5%Si) kahi pūhui peritectic i hana ʻia ma waena o Ca a me CaSi ma nā mahana ma lalo o 910°C. ʻO CaSi2 (58.36%Si) kahi pūhui peritectic i hana ʻia ma waena o CaSi a me Si ma nā mahana ma lalo o 1020°C. ʻO ka papa hana o nā ʻāpana silika-calcium i hana ʻia ma ka ʻoihana ma kahi o 77% CaSi2, 5% a 15% CaSi, free Si <20%, a me SiC <8%. ʻO ka mānoanoa o ka silicon-calcium alloy i loaʻa ka 30% a 33% o Ca a ma kahi o 5% o Fe ma kahi o 2.2g/cm3, a ʻo ka wela hoʻoheheʻe ʻana mai 980 a 1200 ° C.
