silica

[U] Không đếm được

This term describes a chemical compound rather than a pure element. While silicon is the element, silica refers specifically to the dioxide form, evoking the image of crystalline structures and gritty textures found in nature. In industrial contexts, it carries a connotation of stability and heat resistance. It is viewed as a foundational building block for modern materials, ranging from the transparency of glass to the hardness of semiconductors.

Used exclusively as a mass noun to describe the chemical substance or mineral composition regardless of quantity.
