Silicate minerals

A mineral has a specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids. There are over 5,300 known mineral species. The silicate minerals have composed over 90% of the Earth's crust. The diversity and abundance of the mineral species is controlled by the Earth's chemistry. Silicon and oxygen approximately constitute 75% of the Earth's crust, which translates directly into the predominance of the silicate minerals. Our body needs many minerals.…

Titanium was discovered in 1791 by William Gregor as a inclusion of a mineral in cornwall, it was named for the titans of greek mythology. The name is derived from the titans, the sons of earth goddess of greek mythology. Titanium has 22 protons, 26 neutrons, and 22 electrons. The atomic number of this element is 47,867. Titanium is a lustrous transition metal. William Gregor was a man who was interested in minerals. He recognized the presence of a new element. The boiling point for this element…

The substance we know as asbestos is a combination of six silicate minerals. Asbestos is used commercially for its "wonderful" physical properties, which were perfect for insulation and fire retardant coating. This set of minerals is also used in concrete, bricks, fireplace cement, heating, acid resistant gaskets, fire-proofing drywalls, roofing, lawn furniture, flooring, dry wall joint compounds, as well as insulation in pipes, electronics, and ceilings. Asbestos is also used prominently in…

that there is a crack in the ground before a landslide or mudslide after a odd amount of rain, they look to the building blocks of rocks, minerals. Minerals are what make up all rocks, and there are many types of minerals like quartz which can be seen in most types of sandstone, which is a sedimentary rock. This and other minerals make up rocks, but the minerals themselves are made up of even smaller building blocks like atoms, forming a structure which defines how…

Concrete is a building material that looks like stone. The Latin word “concretus” means to grow together. Concrete is a composite material，composed of coarse granular material (the aggregate or filler) entrenched in a solid matrix of material by (the cement or binder) that fills the space between the aggregate particles and pastes them together. Depending on what kind of binder is used, concrete can be divided into nonhydraulic cement concrete (made of nonhydraulic cement), hydraulic cement…

Quartz is the mixture of silicon and two oxygen molecules (silicon dioxide, or SiO2), it is also the precursor of over 500 stones as they start as the clear quartz and gain their color with inclusions and mineral deposits that are added while forming, these minerals are designated as “silicates.” The Clear Quartz crystal can occur in two different ways, one being the hexagonal crystals in masses and druses, and the other being dense fibrous material that has no visible crystals. Legends say that…

The concrete is the second most used product world-wide after water. The construction industry is one of the vital sectors in the nation’s economy. The concrete mainly contains ordinary Portland cement as a primary binder and production of ordinary Portland cement causes 7% of the total greenhouse gases in to the earth’s atmosphere (Malhotra 2002) and production of the ordinary Portland cement produces carbon-di-oxide in mainly two ways , they are burning of fossil fuels and the other is…

Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…
