Layered hydrous phases such as serpentine (Mg3Si2O5(OH)4), talc (Mg3Si4O10(OH)2), chlorite (Mg5Al(Si3Al)O10(OH)8), and 10 Å phase (Mg3Si4O10(OH)2.xH2O, where x=1,2) play important roles in transporting water into the Earth's interior. Using first principles simulations, we investigate the high-pressure behavior of 10 Å phase. In particular, we investigate the crystal structure of 10 Å phase ...

Talcum Powder [Mg3Si4O10(OH)2] 50 kg Bag. Talcum also refers to Talc. This is a clay mineral that is composed of hydrated magnesium silicate. It appears as an odourless, white to greyish, very fine crystalline powder. It is non-flammable and non-toxic. It is mostly used as a dusting powder, either alone or with starch or boric acid, for toilet ...
Moh's is an ordinal scale and you have to compare two minerals to decide which is harder. For example, corundum has double the hardness as topaz, but diamond is almost four times as hard as corundum. The hardness of a gemstone is measured by finding the hardest material that the material can scratch, or the softest material that can scratch ...
Talc, Mg3Si4O10 (OH)2, reacts with forsterite (Mg,SiO4) to form enstatite (MgSiO3) and water vapor. (a) Write a balanced chemical equation for this reaction. (b) If the water pressure is equal to the total pressure, will formation of products be favored or disfavored with increasing total pressure?
If we bind Si2O5 sheets to both sides of the octahedral layers we can derive additional phyllosilicates which each have t-o-t layers: as for talc, Mg3Si4O10(OH)2, and phyrohyllite, Al2Si4O10(OH)2. In each case it can begin with either brucite or gibbsite, and replace two (OH)- …

Answer: In order to calculate the number of atoms in a molecule, you count the number of subscripts for each element. If there is no subscript, it is understood to be one. In the case of parentheses, you multiply the number of atoms inside the parentheses by the subscript outside the parentheses....

Bulk and slab geometry optimizations and calculations of the electrostatic potential at the surface of both pyrophyllite [Al2Si4O10(OH)2] and talc [Mg3Si4O10(OH)2] were performed at Hartree–Fock and DFT level. In both pyrophyllite and talc cases, a modest (001) surface relaxation was observed, and the surface preserves the structural features of the crystal: in the case of pyrophyllite …
