By DR GARETH SMITH Q MY mum has chronic lung disease and I am worried that the talcum powder she uses may be making it worse. Can it? A IT is unlikely. Talcum-related lung problems happen when the talc has been contaminated with silica.
By Rakovan, John The very first Word to the Wise column dealt with the term pegmatite (Rakovan 2003). This was especially fitting because pegmatites are one of the most important rock types or geologic environments for the production of beautiful and interesting mineral specimens.
Tokyo, July 8 (Jiji Press)--Sekisui Chemical Co. said Tuesday it will boost its production capacity for interlayer films used in automotive laminated glass, aiming at manufacturing enough film annually for 78 million cars, up from the current 66 million.
Biotite is a common phyllosilicate mineral that contains potassium, magnesium, iron and aluminium. It is sometimes called "iron mica" and is found in granitic rocks, gneisses, and schists. Like other mica minerals, biotite has a highly perfect basal cleavage, its flexible sheets easily flaking off. It has a hardness of 2.5 - 3, a specific gravity of 2.7 - 3.1, is colored greenish to brown or black, and can be transparent to opaque. Biotite is occasionally found in large sheets, especially in...
Kaolinite is a mineral with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet linked through oxygen molecules to one octahedral sheet of alumina octahedra. It is also known as china clay and kaolin (é«˜å¶ºåœŸ in pinyin: gao1 ling3 tu3), named after Gaoling ("High Hill"), Jingde Town, Jiangxi, China. It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of feldspar. In...
The mica group of minerals includes several closely related materials having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudo-hexagonal crystals and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. The word "mica" is thought to be derived from the Latin word micare, meaning to shine, in reference to the brilliant appearance...
Muscovite, also known as potash mica, is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets), which are often highly elastic. Muscovite has a hardness of 2 - 2.25 and a specific gravity of 2.76 - 3. It can be colorless or tinted through grays, browns, greens, yellows, or rarely violet or red, and can be transparent or translucent. The green form is called Fuchsite, KAl2(AlSi3O10)(F,OH)2. Muscovite is the most...
Serpentine is a group of common rock-forming hydrous magnesium iron phyllosilicate ((Mg,Fe)3Si2O5(OH)4) minerals. In mineralogy, serpentine may refer to any of 20 minerals belonging to the serpentine group. Owing to admixture, these minerals are not always easy to individualize, and distinctions are not usually made. There are three important aggregate structures of serpentine: antigorite, chrysotile and lizardite. Overview Serpentine is said to owe its name either to its serpent-like...
