The chemical formula of mineral Clinobehoite is indicated by Be(OH)2. Mineral Clinobehoite is usually found occuring in hydrothermally altered zones in desilicated pegmatites. Mineral Clinobehoite is commonly found at its type of locality at Malyshev deposit, Asbest district, near Yekaterinburg (Sverdlovsk), Ural Mountains, Russia. This mineral was named for its monoclinic symmetry and relation to behoite. Mineral Clinobehoite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis. Mineral Clinobehoite is also found showing perfect cleavage in one direction which is more clearly visible when viewed with the aid of petrographic polarizing microscopes. Clinobehoite is usually found colorless and white in hand sample. The density measure of mineral Clinobehoite is usually found 1.93 grams per cubic centimeters. Most crystals of mineral Clinobehoite is usually found transparent to trnslucent in appearance. The hardness measure of mineral Clinobehoite is usually found ranging from 2 to 3 when evaluated using the Mohs scale method. Clinobehoite is also foundd showing vitreous to pearly luster when viewed in reflected light of polarized microscopes. Mineral Clinobehoite is usually found leaving a white streak when rubbed on white porcelain streak plate. Mineral Clinobehoite is also found showing biaxial negative figure with 0.0090 birefringence when evaluated between crossed nicols of petrographic polarizing microscopes used in the field of optical mineralogy. Mineral Clinobehoite is also found not radioactive.
