·The rehydration and rehydroxylation properties of homoionic rectorites saturated with Ca 2 Mg 2 Na or K were further rehydration properties of the rectorite were characterized as follows 1 basal spacings of rehydrated materials after heating above 500°C changed to Å for H 2 O complexes Å for ethylene glycol
·Clay also enhances the reusable efficiency of TiO 2 by making it separable from the reaction mixture Clay minerals such as montmorillonite Mt bentonite kunipia kaolinite smectite rectorite hectorite laponite palygorskite halloysite attapulgite diatomite and layered double hydroxides LDH have been utilized as TiO 2 supports
·The chitosan Ch —bentonite B composite was synthesized and its adsorption properties were investigated for lead ions The characterization of the Ch B composite was clarified by FT IR SEM and pzc studies Factors affecting Pb2 ion adsorption from aqueous solution; pH temperature adsorbent dose adsorbate concentration adsorption time and
·Lanthanum compounds modified rectorite composites for highly efficient phosphate removal from Applied Clay Science IF Pub Date 2020 12 01 DOI /
·Rectorite REC [4] [5] is a kind of clay mineral with structure and characteristics much like those of montmorillonite MMT It is a sort of regularly interstratified clay mineral with alternate pairs of dioctahedral mica like layer non expansible and dioctahedral smectite like layer expansible at ratio of 1 1 in a unit cell
·DOI / Corpus ID 233528565; Bonding mechanism and performance of rectorite/ball clay bonded unfired high alumina bricks article{Li2021BondingMA title={Bonding mechanism and performance of rectorite/ball clay bonded unfired high alumina bricks} author={Xiaohui Li and Huazhi Gu and Ao Huang and
Rectorite clay only films RecF were prepared by the simple device of allowing slow evaporation of aqueous dispersions In this process the exfoliated natural clay sheets self assembled into cohesive films The inorganic films from neat and ion exchanged rectorite clay were translucent and flexible with a layered microstructure and they
·This study investigates the properties and effectiveness of refined diatomite obtained from China in water treatment The refined diatomite has enhanced adsorption and purity Diatomite was observed under the Field Emission Scanning Electron Microscope coupled with Energy Dispersive X ray FESEM EDX to study on its characterization
·In this study the bonding mechanism and normal/high temperature performance of rectorite clay or ball clay bonded unfired high alumina bricks were investigated by using different techniques XRD TG DSC SEM particle size distribution and rheology
·Diatomite also known as diatomaceous earth is a naturally occurring soft siliceous sedimentary rock that is easily crumbled into a fine white to off white powder It is composed of the microscopic remains of diatoms which are single celled algae with skeletons made of silica These skeletons accumulate over time forming deposits of diatomite
· Synthesis of zeolite beta The natural rectorite was depolymerized via a submolten salt SMS system at a temperature of ca 250 °C and the natural diatomite was treated through the thermal activation method as described by Yue et al 2014 Yue et al must be noted that the temperature of the SMS activation is much lower than that of the
·The purpose of this study therefore was to obtain the characteristic apparent density specific gravity absorption single and paired compressive strength of bricks composed of clay and diatomite Five clay to diatomite ratios in volume which are 1 0; ; ; and 0 1 were prepared and tested in accordance
·Clay minerals as abundant natural resources are among the most suitable supporting materials for nano metal In this manuscript new Fe 3 O 4 nanoparticle/rectorite Fe 3 O 4 /rectorite catalysts are developed via in situ precipitation oxidation reaction Various physicochemical characterizations of Fe 3 O 4 /rectorite show that Fe 3 O 4 nanoparticles
