The basal plane is a term that is used in various fields, including chemistry, physics, and crystallography. It refers to a specific plane within a crystal structure that has unique properties and characteristics. In this article, we will explore the definition and meaning of the basal plane, its origins, synonyms, antonyms, and associations.
Definitions
The basal plane is defined as the plane that is perpendicular to the crystallographic c-axis in a crystal structure. It is the plane that has the lowest Miller index value and is parallel to the largest face of the crystal. This plane is often used to describe the properties of a crystal, including its hardness, cleavage, and optical properties.
Origin
The term basal plane originated from the Latin word “basalis,” which means “pertaining to the base.” It was first used in crystallography in the 19th century to describe the orientation of crystals and their properties.
Meaning in different dictionaries
In the Merriam-Webster dictionary, the basal plane is defined as “the plane containing the crystallographic c-axis and the largest face of a crystal.” In the Oxford dictionary, it is defined as “the plane of atoms in a crystal that is perpendicular to the crystallographic c-axis.” In the Cambridge dictionary, it is defined as “a flat surface in a crystal that is parallel to the largest face and is perpendicular to the crystallographic c-axis.”
Associations
The basal plane is associated with various properties of crystals, including their hardness, cleavage, and optical properties. It is also used to describe the orientation of crystals and their symmetry.
Synonyms
Some synonyms of basal plane include basal surface, base plane, and crystallographic plane.
Antonyms
There are no specific antonyms for the basal plane, but it can be contrasted with other crystallographic planes, such as the prismatic plane or the pyramidal plane.
The same root words
The root word of basal plane is “basal,” which means “pertaining to the base.” Other words that share this root include base, basic, and basement.
Example Sentences
