'''硫代硫酸钙'''是[[钙]]的[[硫代硫酸盐]]，化学式 {{chem|CaS|2|O|3}}。

== 制备 ==
硫代硫酸钙可以由[[硫代硫酸钠]]和[[氯化钙]]反应而成。{{cn}}
:<chem>CaCl2 +  Na2S2O3 -> CaS2O3 + 2 NaCl</chem>

它的六水合物可以从[[硫代硫酸]]制备。<ref>{{cite journal | last=Ballczo | first=H. | last2=Kaufmann | first2=O. | title=Calciumthiosulfat: Seine Darstellung, Eigenschaften und Zersetzung | journal=Monatshefte für Chemie | volume=80 | issue=2 | date=1949 | issn=0026-9247 | doi=10.1007/BF00906465 | pages=220–231 | language=de}}</ref>

它也可以由[[亚硫酸钙]]和[[硫]]在 30–40&nbsp;°C 下或是沸腾的[[氢氧化钙]]和硫在[[二氧化硫]]下反应而成。<ref name="HSDB">{{HSDB|ID=2507|Name=Calcium thiosulfate|Abruf=2019-04-05}}</ref>

== 性质==
硫代硫酸钙是一种无色晶体，其六水合物可溶于水。<ref name="William M.
