Abstract

Thermal properties of gem stones play an important role in measurement of the physical properties such as its thermal conductivities. The thermal conductivity is a measurement of the material’s ability to conduct heat. The research work analyses thermal conductivity and electrical conductivity of ten special stones namely; Tourmaline, moscovite, feldspar, and quartz (SP1), Lithium, feldspar and quartz (SP2), Gneiss with chlorization (SP3), Pegmatic Rock (SP4), Quartz weathering (hermatization) (SP5), Pegmatite with lithium (SP6), Quartz with feldspar ironization (SP7), Schist (SP8), Gabbro with iron content (SP9), Quartz with stain of feldspar (SP10). The transient hot wire method was adopted since it is one of the most suitable methods to measure the thermal conductivity due to its very cheap cost of construction, accuracy and fast method of measurement. The implementation requires accurate temperature sensing, automatic control, data acquisition and data analysis. The results of the research work show that the thermal conductivity and electrical conductivity in some of the gem stones correlated (SP1, SP2, SP4, SP7, SP8 and SP10). However, it is not the same case with other gem stones (SP3, SP5, SP6, SP9). This could be because conductivities depend on the material's composition, structure, and temperature. Therefore, it is possible for some materials to have good thermal conductivity but poor electrical conductivity due to its wide bandgap. Such materials with good thermal conductivity and poor electrical conductivity are useful for heat sinks, electronic packaging, and thermal interfaces.
