Fig. 6From: Composition, Respirable Fraction and Dissolution Rate of 24 Stone Wool MMVF with their BinderSummary of measured dissolution rates k [Si,Al, ng/cm2/h] as a function of the compositional parameters a,b of the molar ratio Al / (Al + Si) or c,d of KI. The flow rates are identical throughout, and the pH is a,c pH 4.5 and b,d pH 7.4. The materials with highest k at pH 4.5 (MMVF #1, MMVF #5) were also screened at pH 7.4 and are included in the plotBack to article page
