What is the common name for calcium silicate?
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2. It is also referred to by the shortened trade name Cal-Sil or Calsil. It occurs naturally as the mineral larnite.
Which is Pyrosilicate?
Sorosilicate, formerly called pyrosilicate, any member of a group of compounds with structures that have two silicate tetrahedrons (each consisting of a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) linked together.
What is the chemical name of SiO3?
The chemical name for talcum powder is hydrated magnesium silicate. The chemical formula for hydrated magnesium silicate is H2Mg3 (SiO3)4.
What is si2o5?
The phyllosilicates, or sheet silicates, are an important group of minerals that includes the micas, chlorite, serpentine, talc, and the clay minerals. The basic structure of the phyllosilicates is based on interconnected six member rings of SiO4–4 tetrahedra that extend outward in infinite sheets.

What are silicates give an example?
The vast majority of the minerals that make up the rocks of Earth’s crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals.
What are the six main silicate structures?
Key Concepts Silicate minerals are the most common of Earth’s minerals and include quartz, feldspar, mica, amphibole, pyroxene, and olivine. Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.
What are the two types of silicates?
TYPES & CLASSIFICATION OF SILICATES Ortho silicates (or Nesosilicates) Pyro silicate (or Sorosilicates) Cyclic silicates (or Ring silicates) Chain silicates (or pyroxenes) Double chain silicate (or amphiboles) Sheet or phyllosilicates. Three dimensional (or tecto) silicates.
