Therefore, either the cuprokalininite or bornite minerals could prove ideal thermoelectricponents. Half-Heusler alloysSimilar to the production of lime, magnesite can be burned in the presence of charcoal to produce MgO, which, in the form of a mineral, is known as periclase. Large quantities of magnesite are burnt to make magnesium oxide: an important refractory (heat-resistant) material used as a liningnerators.
