The chemical composition of mineral Becquerelite is indicated by the formula Ca(UO2)6O4(OH)6•8(H2O). Mineral Becquerelite is also most commonly found at sedimentary uranium deposit. Becquerelite is also commonly found at its type of locality at Kasolo, Belgian Congo. Mineral Becquerelite was named for French physicist Antoine Henri Becquerel (1852-1908), who discovered radioactivity in 1896. Mineral Becquerelite is also most commonly found crystallizing in the orthorhombic system of crystal formation. In optical mineralogy, this orthorhombic crystal system comprises crystals having three mutually perpendicular axes, of which all are of different lengths.

Mineral Becquerelite is most commonly found showing perfect cleavage in two different directions which can be found more cleary visible when viewed closely under polarizing microscope used in the field of optical mineralogy.  Becquerelite is commonly found colored brownish yellow, golden yellow, orange or lemon when viewed closely under polarizing microscope used in the field of optical mineralogy. The specific gravity measure of mineral Becquerelite is most commonly found 5.14 grams per cubic centimeters. Most crystals of mineral Becquerelite are found transparent to translucent in appearance. The crystal habit of mineral Becquerelite as described in the field of optical mineralogy usually includes crystalline to fine structures occuring as well-formed fine sized crystals when viewed under polarizing light microscope used in the field of optical mineralogy. The hardness measure of mineral Becquerelite when specimen is evaluated closely using the Mohs scale method is usually found 2.5. Most Becquerelite crystals are found non-fluorescent when evaluated under polarized microscope for mineralogists. Becquerelite is most commonly found exhibiting resinous luster when viewed in reflected light of poalrizing microscope used in the field of optical mineralogy. This mineral is most commonly found leaving yellow streak when rubbed on a white porcelain streak plate. Mineral Becquerelite is usually found exhibiting biaxial negative figure when viewed closely between crossed nicols of petrographic polarizing microscope. Becquerelite is also commonly found showing 0.1300 birefringence. Mineral Becquerelite is also found pleochroic and usually appear colorless, yellow and deep yellow when viewed closely with the aid of polarizing microscope for mineralogists. Mineral Becquerelite is found to be radioactive as evaluated.
