Chemical formula of smaltite
A
CoAs3
B
CoAs4
C
CoAs2
D
CoAs
Explanation: 

Detailed explanation-1: -Smaltite is a variety of the mineral skutterudite consisting of cobalt, iron, nickel, and arsenide. It has the chemical formula (Co, Fe, Ni)As 2.

Detailed explanation-2: -2008, Sato et al. 2008). The term skutterudite originally refers to a naturally occurring mineral with the chemical formula CoAs3, which was mined as a source of cobalt and nickel in Skutterud, Norway. The skutterudite mineral structure was originally characterized in 1928 by I.

Detailed explanation-3: -It is mined as an ore of cobalt and nickel with a by-product of arsenic. The crystal structure of this mineral has been found to be exhibited by several compounds with important technological uses. The mineral has a bright metallic luster, and is tin white or light steel gray in color with a black streak.

Detailed explanation-4: -It is a rare, dense mineral which can sometimes contain amounts of nickle and iron; it forms by hydrothermal processes in moderate to high temperature environments. Skutterudite can often be found alongside associated minerals such as silver, erythrite, baryte, calcite quartz and many more.

Detailed explanation-5: -What are skutterudites? The defining new ingredients in the proposed eMMRTG are materials called skutterudites, which have unique properties that make them especially useful for power systems. These materials conduct electricity like metal, but heat up like glass, and can generate sizable electrical voltages.
