The phases present in the VM powder, and in coatings exposed to VM, were investigated via Xray diffraction measurements made using a Philips PW1710 diffractometer, with CuK α radiation (λ = nm), 40 kV accelerating current and a 40 mA filament current. The XRD profile is shown in Fig. 3, where it can be seen that the VM powder contains only the expected vermiculite phase.
The maximum compressive strength reached MPa (a rise of % towards the control sample) when 5 wt% of vermiculite was added. Effect of composite orders of graphene oxide on thermal ...
In contrast, we adopted a ballmilling method, which uses vermiculite powder rather than a vermiculite block. Therefore, the present composite materials contained more Ca(OH) 2 and had a higher heat storage density, compared with the composite materials prepared by Kariya et al. [24]. Most importantly, this study realized the regular ...
The nanocellulose (NC) was prepared by ball milling, ... The vermiculite addition showed a similar effect on the hydrogels' thermal stability, as shown in Fig. 4 c, probably because this clay acted similarly to the montmorillonite in the hydrogel network. Although the nanocomposites did not show significant increases in thermal stability, their ...
Vermiculite is hydrous, silicate mineral that is classified as a phyllosilicate and that expands greatly when heated. Exfoliation occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite is formed by weathering or hydrothermal alteration of biotite or phlogopite.
was mechanically mixed in a porcelain ball mill for 12 h to assure complete homogeneity. Preparation of the hardened cement pastes Different cement pastes were prepared using W/S ratio = Each paste was prepared by mixing the dry mix with the required amount of water for about 3 min. After complete mixing, the resultant paste was molded into
The ball mill Ball milling is a mechanical technique widely used to grind powders into ne particles and blend Being an environmentallyfriendly, costeffective technique, it has found wide application in industry all over the world. Since this minireview mainly focuses on the conditions applied for the prep
Ball milling was used to fabricate a nanocomposite of 20% hickory biochar (600°C) and 80% expanded vermiculite (20%BC/VE). This novel composite adsorbent had much higher removal of As (V)...
The natural Mgvermiculite (VB) from Brazil and its Naform (NaVB) was studied after milling in ball, jet and vibrational mills. The morphology of vermiculite samples was studied using scanning electron microscopy (SEM) and the changes of vermiculite structures were monitored using Xray diffraction (XRD) analysis.

Ball milling Vermiculite Biocharbased nanocomposites Arsenic adsorption Wastewater treatment 1. Introduction Arsenic (As) is a ubiquitous "metalloid", abundantly distributed in the continental crust of the earth at concentrations of about mg kg −1 ( National Research, 1977 ).
Further UVvis transmittance and UVaging tests reveal that better UV shielding performance of illite is achieved by suitable ball milling treatment, where the illite lamellar aggregates are vertically breaking down into smaller aggregates, and display 34% increased retention ratio of fabric strength than uncoated fabrics under UV irradiation.
The effect of pyrolysis temperature on the removal of As is complicated. ... (BC/VE) was synthesized via ballmilling biochar with vermiculite [65]. Ball milling reduced the crystallinity of vermiculite, thus increasing the surface adsorption sites of vermiculite. In addition, mechanical activation of ball milling may lead to the storage of ...
The surface changes of vermiculite samples were evaluated using ξpotential measurements as a function of particle electrophoretic mobility (μ). The electrophoretic mobility (μ) of the VB and its milled samples was in the range of to 10. Vermiculite particles characterization after milling in three types of mills.
The effect of ball milling process on the properties of the natural local clay including structural changes and adsorption capacity for the removal of Ni(II) ions from aqueous solutions, was investigated. The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6).

To improve the rough texture and hypoglycemic ability of sea buckthorn insoluble dietary fiber (IDF), a novel combined modification method was developed in this study. The IDF was treated with ball milling and cellulase treatment to obtain comodified insoluble dietary fiber (CIDF). The physicochemical and functional properties of IDF, milled insoluble dietary fiber (MIDF), and CIDF were studied.
Modification of vermiculite was realized by simultaneous ball milling with the presence of two PLA chain extenders, aromatic carbodiimide (KI), and 4,4'methylenebis(phenyl isocyanate) (MDI).

The rotation speed and ballsoil ratio of the ball mill affect the total energy produced by the collision and contact between balls, directly affecting the degradation ability of TPH. The TPH degradation rate of ball milling for 4 h was % at the speed and balltosoil ratio of 500 rpm and 30, respectively.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
BMS/ZVIBC was further synthesized from common agricultural waste maize straw and applied to the adsorption of aqueous tetracycline using a simple ball milling method. SEM, XRD, FTIR, and XPS were used to characterize the structural features and surface properties of BMS/ZVIBC. The effects of time, temperature, pH, and interfering ions on the adsorption were investigated, and the adsorption ...
