Calcium Alloys - an overview | ScienceDirect Topics
Nowadays, these techniques have been widely replaced by wire feeding techniques in which iron-clad calcium wire is fed into the ladle by a wire feeder. The technical idea is always to inject Ca or Ca alloy as deep as possible into the melt in order to have the highest possible ferrostatic pressure in order to minimize the vaporization and to increase the residence time of Ca in the melt.

Superconductivity - Wikipedia
Superconductivity is the set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor.Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has
Mineral Electrical Conductivity | Earth Science Week
People must mine minerals to provide all kinds of materials that we depend on in our lives. The purpose of this activity is to test the conductivity of various minerals with a simple electrical circuit and draw conclusions about which ones would be used in electronics.
