Kolbeckite (scandiumphosphatedihydrate) is a mineral with formula: ScPO4·2H2O. It was discovered originally at Schmiedeberg, Saxony, Germany in 1926 and is named after Friedrich L. W. Kolbeck, a German mineralogist. Kolbeckite is usually found as small clusters of crystals associated with other phosphate minerals.
