On silicate compounds

Between heaven and earth, all things are created, among which silicate compounds are the most important ones.

The so-called silicate compound is a compound system composed of silicon, oxygen and other metals or non-metallic elements. Its variety and complex structure are widely distributed in nature, such as rocks and soils, and many contain such substances. Its chemical properties are stable, and many properties affect all things in the world.

In terms of its related terms, such as silicon-oxygen tetrahedra, this is the basic structural unit of silicate compounds, which is like the cornerstone of a magnificent building. Silicon atoms live in the center, and oxygen atoms surround it to form a stable structure. There is also the concept of degree of polymerization, which is related to the degree to which the silicon-oxygen tetrahedra is connected to each other. Different degrees of polymerization make the properties of compounds very different.

In addition, in terms of crystal structure, there are different structural types such as island, chain, layer, and frame. Island-like silicate, silicon-oxygen tetrahedra exists in isolation, connected to each other by other cations, like islands scattered; chain-like silicate, silicon-oxygen tetrahedra is connected to each other in chains, giving it unique physical properties, either tough or malleable. Layered, silicon-oxygen tetrahedra is connected to form layers, and the interaction between layers is weak, so it often has a good solution, such as the common mica. The framework silicate, silica tetrahedra are connected to each other to form a three-dimensional skeleton structure, so that many of these compounds have high hardness and stability, such as feldspar.

Silicate compounds are also widely used in production and life. In the field of construction, cement, an important building material, its main components contain many silicate compounds, which are hydrated, solidified and hardened to build a solid foundation for high-rise buildings. In ceramic production, the silicate components in clay are fired at high temperature, shaped and qualified, resulting in exquisite and practical ceramic utensils. The manufacture of glass is also inseparable from silicate compounds. By adjusting the ratio of raw materials and processes, glass with different properties can be obtained, or transparent like mirrors, or heat insulation and sound insulation.

Looking at nature, silicate compounds participate in geological changes. Rock weathering, in which silicate has eroded over time, releasing nutrients, nourishing soil, and nurturing all life. Volcanic eruptions, high-temperature molten magma cools and solidifies, forming all kinds of silicate-containing rocks, reshaping the appearance of the earth.

To sum up, silicate compounds and related terms run through nature and human activities, playing an indispensable role in heaven and earth, and it is a material system worthy of further investigation.
