Cordierite/steatite ceramics sintered from talc, kaolin and vermiculites: comparison of natural and organovermiculites effect
Popis výsledku v původním jazyce
The comparable characteristics of the cordierite/steatite ceramic samples sintered from the mixtures containing vermiculites (Ver) from the deposits of Brazil (Ver-S) and Palabora (Ver-P) and the organovermiculites Ver-S/ODA (intercalated in the melt of the octadecylamine, ODA), Ver-P/HTMA (intercalated hexadecyltrimethylamonium, HTMA+) and Ver-P/HDP (intercalated hexadecylpyridinium, HDP+) were studied based on the X-ray powder diffraction mineral phase analysis and porosity measurement. The alkali potassium bounded in the vermiculite structure of Ver-P decrease temperature of the sintering and crystallization of the hexagonal cordierite, indialite, IN < 80 vol.% accompanied by the stable at low temperatures orthoenstatite, OR > protoenstatite, PE. Sintering of mixtures with Ver-S containing lower content of potassium resulted in crystallization of IN > 80 vol.% and PE > OR. The organovermiculites Ver-P/HTMA and Ver-P/HDP prepared from Ver-P dispersed in water by the cation exchange are release of cations from the structure of vermiculite. The cordierite/steatite ceramic samples sintered from the mixtures with Ver-P/HTMA and Ver-P/HDT showed lower content of IN in the favor of OR>PE and reduced porosity. All cordierite/steatite ceramic samples showed dependency of the lattice parameters and quantity of IN on the porosity.
