CO OZNACZA SŁOWO SCHEELITE
Scheelite
Scheelite to minerał wolframianu wapnia o wzorze chemicznym CaWO4. Jest to ważna ruda wolframu. Dobrze ukształtowane kryształki są poszukiwane przez kolektory i czasami są formowane w kamienie szlachetne, gdy są odpowiednio pozbawione wad. Scheelite został zsyntetyzowany w procesie Czochralskiego; wytworzony materiał może być stosowany do naśladowania diamentu, jako scyntylatora lub jako środka do wytłaczania w stanie stałym.
