Potassium sulfate yog cov xim tsis muaj xim crystalline nrog qis hygroscopicity, tsis yooj yim clump, muaj lub cev zoo, thiab yooj yim rau kev thov, ua rau nws zoo heev dej -soluble poov tshuaj chiv. Potassium sulfate kuj yog tshuaj lom neeg nruab nrab thiab physiologically acidic. Nws yog cov tshuaj chlorine -dawb, siab- zoo, thiab muaj txiaj ntsig poov tshuaj chiv, tshwj xeeb tshaj yog tseem ceeb hauv kev cog qoob loo ntawm chlorine- cov qoob loo rhiab heev xws li haus luam yeeb, txiv hmab txiv ntoo, qab zib beets, tshuaj yej ntoo, qos yaj ywm, flax, thiab ntau yam txiv hmab txiv ntoo ntoo; nws kuj yog ib qho tseem ceeb raw khoom rau siab - zoo nitrogen, phosphorus, thiab poov tshuaj (NPK) compound chiv.
Potassium sulfate-raws li cov chiv chiv yog tsim los siv qis-kub hloov pauv ntawm potassium chloride, tshuaj synthesis, thiab tshuaj tsuag granulation txheej txheem. Lawv muaj kev ruaj ntseg zoo thiab tsis tsuas yog muaj peb lub ntsiab lus tseem ceeb (N, P, thiab K) tab sis kuj muaj cov kab mob xws li S, Ca, Mg, Zn, Fe, thiab Cu. Cov chiv no tsim nyog rau ntau cov qoob loo kev lag luam, tshwj xeeb tshaj yog cov uas nkag siab rau chlorine. Cov khoom tseem ceeb ntawm cov poov tshuaj sulfate-raws li cov chiv chiv yog MAP (monoammonium phosphate) thiab DAP (diammonium phosphate), thiab ammonium sulfate (feem ntau tau los ntawm kev ua kom tsis muaj zog sulfuric acid los ntawm qis-kub hloov nrog gaseous ammonia). Potassium sulfate, urea, thiab lwm yam khoom muaj nyob, nrog rau me me ntawm impurities xws li calcium sulfate, hlau, txhuas, thiab magnesium ntsev ntawm phosphate, thiab cov kab ntawm cov poov tshuaj chloride unreacted.
