Halloysite vs kaolinite
WebThe less perfect structure of halloysite and its common curvilinear morphology reduce the difference in stability between hole and associated water molecules, so that when halloysite(10Å) dehydrates, loss of hole water and associated water overlaps, and the d-spacing goes directly to 7.2–7.9 Å. WebWhile kaolin clay is close to the skin’s natural pH of 5.5, bentonite clay sits at around 8.5. This makes it slightly more “basic” on the pH scale, which can help people open their …
