Obtaining  Compounds cannot be obtained in the creative inventory They are only obtained by creating them in the compound creatorThis is done by inserting a certain number of elements corresponding to the compound's chemical formula Unlike ,
Tungsten compounds are expected to exist as ions or insoluble solids in the environment(1) and therefore volatilization from moist soil and water surfaces is not expected to be an important fate process(SRC) Tungsten compounds are not expected to volatilize from dry soil surfaces based upon their ionic character and low vapor pressures(SRC)
Tungsten forms two sulfides with sulfur, WS2 and WS3 The tungsten carbides WC (melting point, 2900° C) and W 2 C (melting point, 2750° C) are solid refractory compounds; they are produced from tungsten and carbon at 1000 °-1500 ° C Preparation and use Wolframite and scheelite concentrates (50-60 percent WO3) are the raw material for the .
