Kaolinite Meaning: Definition and Examples
🪨
kaolinite
[keɪəˈlɪnaɪt ]
Definition
mineral composition
Kaolinite is a layered silicate clay mineral, a major component of kaolin, which is widely used in ceramics, papermaking, and as a filler in various products. It is formed by the weathering of aluminosilicate minerals and is characterized by its fine particle size and white color. Kaolinite has excellent plasticity, which makes it valuable in pottery and other industrial applications.
Synonyms
china clay, kaolin, porcelain clay.
Examples of usage

Origin of 'kaolinite'
Main points about word origin
- The term comes from the Chinese word 'Gaoling', meaning 'high ridge', where this clay was first discovered.
- In the 17th century, European potters adopted the name as they explored and utilized this clay for their products.
The term 'kaolinite' originates from 'Kaoling,' the name of a hill in Jiangxi province, China, where the mineral was first mined for use in ceramics. The name reflects the significant role of China in the early development of porcelain and fine clay products. The suffix '-ite' is commonly used in mineralogy to denote minerals and rocks. Kaolinite was first described scientifically in the early 19th century and has since been studied for its chemical composition, industrial applications, and geological significance. Its discovery has greatly influenced ceramics and material sciences, establishing it as a crucial substance in various industries across the globe.
