CALCIUM SILICATE Meaning and
Definition
-
Calcium silicate is a chemical compound with the formula Ca2SiO4, commonly known as calcium metasilicate. It is a white, odorless powder that occurs naturally in minerals such as wollastonite and can also be synthetically produced.
In terms of its chemical composition, calcium silicate consists of calcium cations (Ca2+) and silicate anions (SiO4) arranged in a three-dimensional lattice structure. This compound possesses a high melting point and is insoluble in water. It is also characterized by its low thermal conductivity and excellent thermal insulation properties.
Calcium silicate is widely used in various applications due to its unique properties. One common application is as a building material. It is used as a structural component in the construction industry to manufacture ceiling and floor tiles, insulation boards, and fire-resistant wall panels. Calcium silicate's ability to withstand high temperatures, along with its flame-retardant properties, makes it an ideal material for use in fire protection systems.
Furthermore, calcium silicate has also found applications in the food and pharmaceutical industries. It is used as an anticaking agent to prevent the formation of lumps in powdered foods, such as spices and instant soups. Additionally, it serves as a dietary supplement containing highly bioavailable calcium, which is essential for maintaining healthy bones and teeth.
In summary, calcium silicate is a chemical compound with various applications due to its excellent thermal insulation, fire-resistant properties, and calcium content. It is widely used in construction, as well as in the food and pharmaceutical industries.
Etymology of CALCIUM SILICATE
The word "calcium" is derived from the Latin word "calx", which means lime or limestone. It is named so due to the element's discovery from limestone.
The word "silicate" is derived from the Latin word "silex", which means flint or hard rock. It refers to compounds that contain silicon and oxygen, such as silicates.
So, when combining "calcium" and "silicate", the term "calcium silicate" refers to a compound that contains both calcium and silicate ions.
