Hydrated silicates are minerals that contain both silicon and oxygen, along with water molecules in their structure. These minerals are formed through geological processes and are commonly found in various types of rocks. They play a significant role in the Earth's crust and can influence soil properties and plant growth. Examples of hydrated silicates include clay minerals and zeolites. These minerals are important in industries such as construction and agriculture. Their unique properties, like water retention and ion exchange, make them valuable for applications ranging from pottery to water purification.
