The 2002 Chemical Economics Handbook reports that the demand for thermal phosphoric acid has been drastically losing ground as wet phosphoric acid becomes preferred for downstream chemicals, that there has also been stiff competition because of imports from China and that many phosphates and direct applications which formerly required thermal phosphoric acid now use purified wet phosphoric acid, with important cost advantages.
aasta väljaandes “Chemical Economics Handbook” väidetakse, et nõudlus termilise fosforhappe järele väheneb drastiliselt, kuna järelseisvate keemiatoodete jaoks eelistatakse märgmenetlusel valmistatud fosforhapet. Peale selle võtvat maad terav konkurents sissevedude tõttu Hiinast.
