This paper studies the influence on compressive strength, freezing resistance and microstructure of cement mortar with different content of mica in stone powder, in the tests, manufactured sand with high content of mica and natural river sand were mixed with different proportion, and the content of stone powder was the same in mixed sand. Experiment results indicate that, with the increasing of mica content in stone powder, 28d and 60d compressive strength of cement mortar decreases obvious, mass loss rate and strength loss rate with 50 freeze-thaw cycles increase a little.

Abstract:
This research is conducted in order to determine the best composition of alumina-cullet ceramic with the addition of mica powder. The alumina-cullet-mica composites (ACMCs) were produced by using powder compaction method. All raw materials used such as alumina, cullet and mica for fabricating the samples were first mixed, compacted and finally the samples have to undergo the sintering process. It is observed from the physical, mechanical and morphological analyses that the properties of ACMCs are highly dependable on the mica content.

Abstract:
AbstractSilicon powder, available as a Standard Reference Material, fulfills most of the requirements for a two theta standard. However, It has no diffraction lines at the low 2θ values characteristic of some species. Standard synthetic mica is available but expensive.Experiments with a commercially available high silica zeolite have shown that it is a valuable secondary standard. It is non-toxic, stable, inexpensive and possesses a large (24 Å) unit cell. Peaks show clearly from 14 Å (6°2θ for Cu Kα).An example is given of the use of this secondary standard in determining lattice parameters.

Abstract:
Present research aims to assess the influence of nanocrystalline mica (NM) dispersion (10, 15, 20, and 25 vol.%) in hydroxyapatite (HA) matrix on its mechanical and tribological properties and bioactivity. Nanosized mica (NM) was prepared by mechanical milling of commercial mica powder. The composite was prepared by mechanically mixing the milled mica with HA and consolidated by microwave sintering at 1200°C for 10 min. Phase characterization by X-ray diffraction (XRD) shows dissociation of HA into β-TCP (tetra calcium phosphate) in sintered compact. Estimated densification is the highest (~98

Chemical data and exchangeable cation determination indicate that K+ is the dominant non-exchangeable interlayer cation, and thus is believed to occupy the mica interlayer site; Mg2+ together with small amounts of Ca2+, Na+ and

A method for quantitative analysis of 3-aminopropyltriethoxysilane (γ-APS) and N-(N-vinylbenzyl-2-aminoethyl)-3-aminopropyltrimethoxy-silane hydrochloride (cationic vinylbenzyl silane, CVBS) on muscovite mica powder has been developed with the use of diffuse reflectance FT-IR spectroscopy. The adsorption isotherms determined by this method are reported. The results are compared with a previous study of the adsorption of aminosilanes by ESCA, and possible models of the adsorbed layer are discussed.

Abstract:
Many Middle Stone Age (MSA) sites have evidence of the regular collection and use of ochre. Sibudu (KwaZulu- Natal, South Africa) has a large MSA ochre assemblage of over 9000 pieces from layers dating between ~77 ka and ~38 ka. There are 682 pieces with signs of use. All usetraces were examined and activity categories were defined based on published ochre experiments. The most frequent markings on ochre pieces are grinding striations that are smoothed by subsequent rubbing. Grinding and rubbing also occur independently on many pieces. Scored pieces are rare, but are more common in the pre-Sti

Through scraping and baking, the thick film coating on the treated aluminum alloy was obtained. The optimum range of P/B (weight ratio of the pigment/binder) was determined to be 0.75:1 by investigating the influence of the P/B on the liquidity and thickness of the coating, indicating that the thickness of the coating reached 500μm.

A UV curable coating modified by several inorganic particles was prepared and characterized. Several kinds of inorganic particles including glass powder, mica, alumina, talcum powder and polyimide were introduced to epoxy acrylate (EA) as fillers and mixed with reactive diluent, photoinitiators, and other additives to obtain an organic-inorganic ultraviolet (UV) curable coating. Different kinds of inorganic powders were mixed in proportion to the formula and ground in a ball mill for 16 h to obtain smaller particles. The particle size and morphology of inorganic powders were characterized by l
