Key Characteristics

Characteristics of Krutovite

Krutovite is opaque grayish white paler then the color of nickel skutterudite. In reflected light the mineral has a vivid white with a rosy tint. It has a hardness of 5.5 on the Mohs scale and a metallic luster. No cleavage is observed. Krutovite has high degree of reflectance about 64.0-67.0% higher than known nickel arsenides and sulfarsenides. The spectrum of reflectance that occurs in krutovite has a wavelength range of 440-1100 and a minimum of 480-540 nm. The rose tint gives the small increase of reflectance in the violent and red parts of the spectrum.

Composition of Krutovite

Krutovite is from the family of the isometric-dipoloidal system (2/m3) and is known to have the same structure type as gersdorffite type P213. Krutovite and gersdorffite form a solid solution at a temperature of less than 300 °C (572 °F).
