What are some minerals in silicates?
Some minerals in silicates include quartz, feldspar, mica, amphibole, and pyroxene. These minerals are characterized by their crystalline structure composed of silicon and oxygen atoms arranged in tetrahedra.
What has the author I A Voinovitch written?
I. A. Voinovitch has written: 'L' analyse des silicates' -- subject(s): Silicates 'The analysis of silicates' -- subject(s): Silicates
Describe the six main crystalline structures of silicate minerals?
Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
What sre uses of silicates?
Silicates are used in a variety of applications such as making glass, ceramics, and cement. They are also used in the manufacturing of detergents, paper, and as fillers in paints and plastics. Additionally, silicates are utilized in the production of silicones and as a component in some building materials.
What are the two major mineral grouped?
Silicates and non-silicates.
What are the two most common kinds of minerals?
Silicates and non-silicates.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian silicates contain iron and magnesium in their composition, which gives them a dark color and high density. Non-ferromagnesian silicates do not contain iron and magnesium, resulting in lighter colors and lower densities. Ferromagnesian silicates tend to be denser and have higher melting points compared to non-ferromagnesian silicates.
How do sheet silicates differ from framework silicates?
Sheet silicates have a layered structure where silica tetrahedra are arranged in sheets with cations between the layers, while framework silicates have a three-dimensional network of silica tetrahedra connected in all directions. Sheet silicates have weaker bonds between layers, allowing for easier cleavage and flexibility, while framework silicates have stronger bonds, resulting in a more rigid structure.
How do you extract silicates from its ore by aquaregia?
Silicates cannot be extracted from ore using aqua regia as it is not effective in dissolving silicates. Silicates are typically extracted using a different process, such as leaching with acids like hydrochloric acid or sulfuric acid, or by fusion with alkali compounds.
How many oxygen atoms are in single chain silicates?
Single chain silicates have a chemical formula of Al2SiO5. Therefore, there are a total of 5 oxygen atoms in single chain silicates.
What are two big groups of minerals called?
Silicates and non-silicates are the two big groups of minerals. Silicates are the most abundant mineral group on Earth and contain silicon and oxygen, while non-silicates include minerals such as carbonates, sulfides, oxides, and native elements.
What are dark silicates?
Dark silicates are minerals that contain a combination of silicon and oxygen, along with other elements like magnesium and iron. They have a dark or black color due to the presence of these metal elements, which absorb light. Dark silicates are commonly found in basaltic rocks, volcanic ashes, and in some meteorites.
