Surface Layer Types of Kaolinite: A High-Resolution Transmission Electron Microscope Study
2:1 Layer Clays HRTEM Kaolinite Pyrophyllite Smectite Surface Layer
2011/12/6
Abstract: High-resolution transmission electron microscopy (HRTEM) examinations have indicated that three types of surface layers may exist in natural kaolinite crystals. Type 1 has the expected 7-侌 s...
Effectiveness of different types of clay for reducing the detrimental effects of aflatoxin-contaminated diets on performance and serum profiles of weanling pigs
Pigs Aflatoxins Bentonite Zeolites Sepiolite Palygorskite
2011/11/7
Three trials were conducted with recently weaned pigs (n = 198) to determine the effects of feeding different types of clay in conjunction with aflatoxin-contaminated diets. In Trial 1, pigs (n= 54; t...
Parameters Influencing Layer Stacking Types in Saponite and Vermiculite: A Review
Layer charge Layer stacking Relative humidity Saponite Vermiculite
2012/1/11
Saponites and vermiculites may assume at least 11 ordered or semi-ordered layer stacking sequences. For a given relative humidity, the layer stacking type assumed is a function of the nature of the in...
