Kalorimet

Kalorimet is a naturally occurring mineral noted for its capacity to store and release thermal energy through reversible structural changes. The name combines references to heat with a mineral-typical suffix, and it was first described in the early 1990s by geologists investigating geothermal activity in the Ural Mountains of Russia. Since then, small, sporadic deposits have been documented, making Kalorimet a topic of interest in mineralogy and energy-storage research.

Chemically, Kalorimet is a hydrated calcium- and iron-rich silicate with variable aluminum and manganese content. A representative formula is written as (Ca,Na)2(Fe,Mn)Si4O10·nH2O, reflecting compositional variability across samples. It crystallizes in the monoclinic system and forms prismatic, translucent to opaque crystals. Typical physical properties include a Mohs hardness around 5 and a specific gravity in the mid-3 range. Color ranges from pale blue to olive green, and the mineral generally has a vitreous to subvitreous luster.

Occurrence and formation occur in hydrothermal environments within granitic and metamorphic rock settings. Kalorimet is commonly found in veins with quartz, epidote, magnetite, and calcite, and it is associated with low-temperature, high-alkalinity fluids that alter surrounding minerals. Known localities include the Ural region and select volcanic and high-milience zones in Iceland and the Andes, though overall occurrences are limited and irregular.

Uses and significance center on Kalorimet’s energy-storage properties. Research explores its potential in thermal buffering materials and phase-change applications for buildings and industrial heat management. Current production is scarce and largely experimental or pilot-scale, with no large-scale mining established. Safety considerations are typical for mineral handling, including precautions against inhalation of fine dust. Environmental impact is considered moderate, pending advances in synthesis and scalable processing.
