Tsarkake Ruɓaɓɓen Karfe Karfe Haɗakar Ƙarfe Mai Haɗaɗɗen Ƙarfe Silicon Calcium Alloy Calcium Silicon Alloy

Garin binary wanda ya ƙunshi silicon da calcium yana cikin nau'in ferroalloys. Babban abubuwan da ke tattare da shi sune silicon da calcium, sannan kuma yana dauke da datti kamar iron, aluminum, carbon, sulfur da phosphorous mabambanta. A cikin masana'antar ƙarfe da ƙarfe, ana amfani da shi azaman ƙari na calcium, deoxidizer, desulfurizer da denaturant don abubuwan da ba na ƙarfe ba. Ana amfani dashi azaman inoculant da denaturant a cikin masana'antar simintin ƙarfe. Dangane da siliki-calcium gami, ana ƙara wasu abubuwa don samar da gawa mai haɗaɗɗun nau'i na ternary ko multi-element. Kamar Si-Ca-Al; Si-Ca-Mn; Si-Ca-Ba, da dai sauransu, ana amfani da su azaman deoxidizer, desulfurizer, denitrification wakili da alloying wakili a cikin ƙarfe da ƙarfe ƙarfe.

Calcium ƙarfe ne na ƙasa na alkaline tare da nauyin atomic na 40.08, tsarin lantarki na waje na 4S2, girman (20°C) na 1.55g/cm3, wurin narkewa na 839±2°C, da kuma wurin tafasa na 1484° C. Dangantakar da ke tsakanin tururin matsa lamba na calcium da zafin jiki shine

Inda pCa shine matsa lamba na alli, Pa; T shine zafin jiki, K. Silicon da calcium suna samar da mahadi guda uku, wato CaSi, Ca2Si da CaSi2. CaSi (41.2% Si) ya tsaya tsayin daka a babban yanayin zafi. Ca2Si (29.5% Si) wani fili ne na peritectic da aka kafa tsakanin Ca da CaSi a yanayin zafi ƙasa da 910°C. CaSi2 (58.36% Si) wani fili ne na peritectic da aka samar tsakanin CaSi da Si a yanayin zafi ƙasa da 1020°C. Matsakaicin adadin abubuwan da ake samarwa na silicon-calcium alloys kusan 77% CaSi2, 5% zuwa 15% CaSi, Si <20%, da SiC <8%. Girman siliki-calcium gami mai ɗauke da 30% zuwa 33% na Ca da kusan 5% na Fe shine kusan 2.2g/cm3, kuma zafin narkewa yana daga 980 zuwa 1200 ° C.
