The chemical formula of mineral Albrechtschraufite is indicated by Ca4Mg(UO2)2(CO3)6F2-17(H2O). Mineral Albrechtschraufite is usually found as museum specimen of schrockingerite. Albrechtschraufite is most commonly found at its type of locality at Jachymov, Zapadocesky, Czech Republic. The mineral was named after the Austrian crystallographer, Albrecht Scrauf of the Univesity of Vienna, Vienna, Austria. Albrechtschraufite is known to crystallize in the triclinic system of crystal formation. In optical mineralogy, this triclinic crystal system commonly comprises crystals having three axes, of which all are unequal in length and are positioned oblique to one another.

            Mineral Albrechtschraufite is most commonly found colored yellow green in hand sample and it is usually exhiobiting splendid images when viewed with the aid of petrographic poarizing microscopes used in the field of optical mineralogy. The specific gravity measure of the mineral Albrechtschraufite is usually found 2.6 grams per cubic centimeters. The hardness measure of the mineral when it is evaluated using the Mohs scale method is usually found 2.3. When evaluated in reflected light of polarized microscope, mineral Albrechtschraufite is usually found showing vitreous luster. Albrechtschraufite is most commonly found leaving a white streak when rubbed on a white porcelain streak plate. Albrechtschraufite is a radioactive mineral. Therefore, it should be stored away from other minerals that are easily affected by radioactivity. Human exposure should be also limited.
