The chemical formula of mineral Calciobetafite is indicated by CaZrSi3O9•3(H2O). this mineral is most commonly found in miarolitic cavities in a perialkalic alaskitic border granite of batholith. Mineral Calciobetafite is also most commonly found at its type of locality at Washington Pass, on Liberty Bell Mountain, Okanogan Co., Washington, USA. Calciobetafite was named for the “calcium” content and relation to “hilairite.”. Mineral Calciobetafite is known to crystallize in the trigonal system of crystal formation.

Calciobetafite has no cleavage display even if it is closely evaluated between crossed nicols of polarizing microscope used in the field of optical mineralogy. Mineral Calciobetafite is most commonly found colored blue white or white in hand sample. The specific gravity measure of mineral Calciobetafite is usually found 2.68 grams per cubic centimeters. Most crystals of mineral Calciobetafite are found translucent in appearance. The hardness measure of mineral Calciobetafite when it is evaluated closely using the Mohs scale method is usually found 4. Mineral Calciobetafite is most commonly found showing vitreous or glassy luster when evaluated in reflected light of polarized microscope for mineralogists. Mineral Calciobetafite is usually found leaving a white streak when rubbed on white porcelain streak plate. Calciobetafite is commonly found showing uniaxial negative figure when rubbed on a white porcelain streak plate. Calciobetafite is also commonly found showing birefringence of about 0.0030. Calciohilairite is a non-radioactive mineral as evaluated.
