silíceo
Silíceo is a Spanish term that can refer to several related concepts, primarily concerning the element silicon or silicon-based materials. In a chemical context, it is often used as an adjective meaning "siliceous," indicating something derived from or containing silicon dioxide (silica). This can apply to minerals, rocks, or compounds that are rich in silica.
More broadly, "silíceo" can also be used informally to describe materials or processes related to silicon technology.
The etymology of the word traces back to "silica," which itself comes from the Latin word "silex,"
