Abstract

Praškasta smjesa vapna koja sadrži čestice kalcijevog hidroksida sa specifičnom površinom, izračunatom BET metodom, jednakom ili većom od 25 m2/g i ukupni volumen pora, izračunat BJH metodom desorpcije dušika, jednak ili veći od 0.1 cm3/g, naznačena time što dalje sadrži alkalijske metale u količini jednakoj ili većoj od 0.2% i jednakoj ili manjoj od 3.5% na temelju ukupne težine smjese. Patent sadrži još 14 patentnih zahtjeva.
