A unique vanadium-titanium-bearing mixed-layered clay is currently being mined as an ore of vanadium at Potash Sulphur Springs, AR. The clay contains 80% expandable portion and has both a 14.22 and 18.24 Å hydration state in addition to the 9.49 Å dehydrated state; ethylene glycol expands this material to 16.69 Å. The 060 reflection for all hydration states is between 1.50 and 1.51 Å indicating the material is dioctahedral. The “mean chemical formula” calculates as(Ca0.08 K0.02 Na0.03)0.13 (Al0.11 V0.90 Ti0.19 Fe0.64 Mg0.14)1.98 (Si3.79 Al0.21)4 O10 (OH)2·nH2O.

Резюме

Резюме

Уникальная ванадий-титаносная смешанно-слойная глина в настоящее время добывается в качестве руды ванадия на месторождении Поташ Сульфа Спрингс, Ap. Глина включает 80% расширяемой части и имеет гидратные состояния 14,22 и 18,24Å в дополнение к дегидратному состоянию 9,49Å. Этиленгли-коль расширяет этот материал до 16,69Å. Отражение 060 для всех гидратных состояний находится между 1,50 и 1,51Å, указывая, что материал является ди-октаэдрическим. “Средняя химическая формула” вычислена в виде(Ca0.08 K0.02 Na0.03)0.13 (Al0.11 V0.90 Ti0.19 Fe0.64 Mg0.14)1.98 (Si3.79 Al0.21)4 O10 (OH)2·nH2O.

Kurzreferat

Kurzreferat

Ein einmaliger, Vanadin-Titan haltiger, gemischt-Schicht Ton wird im Augenblick als Vanadinerz in Potash Sulphur Springs, Ar. abgebaut. Der Ton besteht zu 80% aus schwellbarem Teil, und hat nicht nur einen 14,22A und einen 18,24A Hydratationszustand, sondern auch einen 9,49 A Dehydratationszustand. Athylenglykol expandiert dieses Material bis auf 16,69A. Die 060 Reflektion für alle Hydratationszustände ist zwischen 1,50 A und 1,51A, was andeutet,daß das Material dioktahedrisch ist. Die durchschnittliche chemische Formel wurde ausgerechnet als:(Ca0.08 K0.02 Na0.03)0.13 (Al0.11 V0.90 Ti0.19 Fe0.64 Mg0.14)1.98 (Si3.79 Al0.21)4 O10 (OH)2·nH2O.
