Izintengo ze-tungsten powder kanye ne-ammonium metatungstate (APT) e-China zigcina uzinzo lapho indali yamasheya e-ammonium paratungstate evela e-Fanya metal exchange ingakacaci.

Izibopho zezomnotho nezohwebo zamazwe ngamazwe nazo zineziyaluyalu, ngakho yonke imakethe ibambeke emoyeni wokulinda futhi ubone ngenani elilinganiselwe lokuhweba.Imakethe ye-molybdenum concentrate inamanani kodwa akukho ukuthengiswa, okusekelwa izindleko eziphezulu kanye nokukhuphuka okuqinile kwengqondo yabathengisi.ngaphezu kwalokho, ukuhlolwa kwemvelo kwamaShayina kwenza ukunikezwa kwezinto ezingavuthiwe kuqine.Amafekthri ancibilikisayo ahlala enezinga eliphansi lokusebenza emakethe ye-APT ethintwa isidingo esibuthakathaka kanye nezingozi zokuguqulwa kwentengo.
