1. Hoʻohana ʻia ia no ka hana ʻana i ka tungsten metala, tungstic acid a me nā paʻakai tungstate. Hoʻohana ʻia e like me ka mordant, pigment a catalyst. Hiki ke hoʻohana ʻia e like me ka lole pale ahi a me ka analytical chemical reagent.
2. Hoʻohana ʻia kēia huahana ma ke ʻano he mea kōkua lole, a ua hoʻohana ʻia ka hui ʻana o ka sodium tungstate, ammonium sulfate a me ka ammonium phosphate no ka pale ʻana i ke ahi a me ka wai ʻole o ka fiber. Hiki ke hana ʻia kēia fiber i lāʻau ahi a me ka rayon. Hiki ke hoʻohana ʻia no ke kaupaona ʻana i ka lole, ka ʻili ʻili, ka pale ʻana i ka corrosion coating electroplating. Hiki ke hoʻohana ʻia kēia huahana ma ke ʻano he cosolvent e hōʻemi i ka mahana ahi a hoʻokō i ke kala.
25kg DRUM a i ʻole koi o nā mea kūʻai aku. E mālama iā ia mai ka mālamalama ma kahi mahana ma lalo o 25 ℃.
