The chemical formula of Cacoxenite is indicated by Fe24(AlO6)(PO4)17(OH)12-75H2O or Hydrated Iron Aluminum Phosphate Oxide Hydroxide. Cacoxenite is actually a Phosphate mineral. The name of Cacoxenite was actually derived from a Greek word for bad guest. This is relative to the property of Cacoxenite mineral where its phosphorous content lessens the quality of the smelted iron. Cacoxenite mineral species was actually first discovered in the year 1825 at Bohemia in the Czech Republic. Cacoxenite is known to crystallize in the hexagonal system of crystal formation. In optical mineralogy, the hexagonal system of crystallization comprises crystals having four axes. Three of which are positioned in a single plane with equal length and are symmetrically spaced. The fourth axis is found to be perpendicular to the other three axes.
Cacoxenite is most commonly found as an inclusion in some attractive minerals such as amethyst and quartz that are commonly found exhibiting attractive and interesting microscope images under petrographic polarizing microscopes used in the fieldof optical mineralogy. Cacoxenite inclusion in Amethyst is often found detracting from the Amethyst as the brown acicular needles dampen the pure purple color to a less desirable brownish shade, which can be seen more clearly visible when viewed with the aid of polarizing light microscope for mineralogists. If Cacoxenite is found as an inclusion in a certain host stone, it will certainly ruin whatever chance the host stone has to become a gemstone. But this do not actually mean that some specimens of Cacoxenite included Quartz have no value. They are actually found enhanced with interesting surreal landscaping effects.
Cacoxenite is actually appreciated as a scarce phosphate mineral on its own way. It is also known from localities of classic phosphates. Cacoxenite can therefore represent some very nice mineral specimens that are usually found exhibiting a splendid microscope views under a polarizing light microscope. These specimens of Cacoxenite can be actually quite popular and attractive with a silky luster in reflected light of geological microscopes and also a typical yellow brown color in transmitted light of polarized light microscopes. Cacoxenite crystals can actually make for visually spectacular stones that can be used in jewelry. They can actually display a fascinating microscope image under a polarizing light microscope.
Cacoxenite is most commonly found in shades of yellow brown, brown, and reddish yellow also greenish yellow or yellow in transmitted light of petrographic polarizing microscope used in optical mineralogy. Cacoxenite is also most commonly found exhibiting a vitreous to silky luster when it is viewed in reflected light of polarized microscopes for mineralogists. Cacoxenite is also most commonly found showing a poor cleavage when mineral specimen of is evaluated between crossed nicols of polarizing light microscope for mineralogists. Cacoxenite is also usually found showing fibrous fracture when specimen is examined under several adjustments on the aperture diaphragm of the polarizing microscope used in optical mineralogy. The specific gravity measure of mineral specimen Cacoxenite commonly gives an approximate value of 2.3 grams per cubic centimeters, which is considered below average. The hardness measure of Cacoxenite when it is evaluated using the Mohs scale method is usually found in a range of 3 to 4. Cacoxenite is also most commonly found leaving a yellow streak when mineral specimen is rubbed on a white porcelain streak plate.
Cacoxenite mineral crystals are commonly found translucent to transparent in appearance. The crystal habit of Cacoxenite as described in the field of optical mineralogy commonly includes acicular radiating crystals, which are often found as inclusions in some attractive and interesting minerals. Cacoxenite minerals can be also found in massive forms, globular and sometimes as botryoidal and fibrous tufts, which are usually interesting to view under polarized light microscope for mineralogists. Cacoxenite mineral species is also most commonly found exhibiting a maximum birefringence at 0.060 when specimen is evaluated between crossed nicols of petrographic polarizing microscope. Cacoxenite is also most commonly found showing uniaxial positive figure when the mineral is viewed between crossed nicols of polarizing light microscope for mineralogists. The refractive indices of Cacoxenite are commonly found ranging from 1.580 to 1.650. Cacoxenite is also found showing a moderate surface relief when it is closely viewed with the aid of petrographic polarizing light microscope used in optical mineralogy. There is no specific data on the toxicity and health dangers for mineral Cacoxenite. However, the specimens of Cacoxenite mineral should be treated with great care and use of sensible precaution is advised upon handling them.
Cacoxenite is also found commonly associated with several interesting and attractive rare phosphates and are commonly producing nice piece of specimen that is very interesting to view under polarized microscopes. Cacoxenite minerals are commonly associated with interesting minerals such as hematite, quartz, limonite, strengite, rockbridgeite and beraunite. The best field indicators of mineral Cacoxenite commonly include color, density, crystal habit, streak and its wonderful association with several other interesting minerals. Cacoxenite minerals notably occur at some famous localities like Sweden, France, some areas in the United States such as Indian Mountain, Alabama and the Coon Creek Mine in the Polk County in Arkansas as well as in Cornwall, England and in Hagendorf, Germany.
