Fig. 7From: Temperature- and humidity-induced changes in alum-treated wood: a qualitative X-ray diffraction studyK-alum:KHSO4 during RH cycle (C), intensity in square root scale. At initial RH of 15% with K-alum and KHSO4 references are also shown. At unstable high RH many KHSO4 peaks disappear. At the final 50% RH KHSO4 peaks have reappeared with drastic changes in relative intensities, and inverted triangles mark new peaks not accounted for by K-alum and KHSO4 referencesBack to article page
