Chromite - Wikipedia

Chromite, when alloyed with iron and nickel creates an alloy called nichrome. Nichrome is described as being 80% nickel and 20% chromium. Due to the alloys that make nichrome, nichrome is seen to be heat resistant up to temperatures of 1250 °C (2282 °F). Due to the high heat resistance of nichrome, it is mainly used for heating units. Nichrome alloys also have very good mechanical properties ...

Heat Capacities of Minerals - Chemistry LibreTexts

The specific heat capacities of minerals can be estimated by adding the heat capacities of the constituent atoms. This method accentuates the fact that the heat capacity depends on the number of atoms present in the sample. The heat capacity of quartz is thus calculated from values in the table below: C V (silicon) + 2 x C V (oxygen) = C V (quartz) ~ C P (quartz) 15.9 +
