Kalcijev karbid: Kakšen je proizvodni postopek kalcijevega karbida?
Kemijsko ime kalcijevega karbida je kalcijev karbid, njegova molekularna formula pa je CAC 2. Kemično čisti kalcijev karbid je skoraj brezbarven in prozoren . izjemno čisti kalcijev karbid je nebesno modro veliko kristalov, enaka barva kot ugašano jeklo .
The main components of industrial calcium carbide are calcium carbide, and the rest are free calcium oxide, carbon, and compounds of silicon, magnesium, iron, and aluminum, as well as a small amount of phosphide and sulfide. The purity of industrial calcium carbide is about 70%-80%. The appearance is gray, brown, purple or black solids depending on the content of calcium carbide. Those with higher calcium carbide content are purple. Its newly created cross-section is shiny, and it absorbs moisture in the air and is gray or grayish white. The chemical properties of calcium carbide are very active. It decomposes violently in water Za proizvodnjo acetilenskega plina in kalcijevega hidroksida in sprošča veliko toplote .
