si-li-cát
Definition
- Noun:
- Silicate: A salt or ester derived from silicic acid, containing the anion SiO₄⁴⁻ or similar structures. Silicates are a major component of many rocks, minerals, and manufactured materials like glass and ceramics.
Usage Examples
- Noun:
- Thạch anh là một loại khoáng vật si-li-cát phổ biến. (Quartz is a common silicate mineral.)
- Hầu hết các loại đá trong vỏ Trái Đất đều chứa si-li-cát. (Most rocks in the Earth's crust contain silicates.)
- Kính được sản xuất từ nguyên liệu chính là si-li-cát. (Glass is produced from silicate as a primary raw material.)
Advanced Usage
- In geology and chemistry, "silicate" refers to the extensive class of compounds structured around silicon-oxygen tetrahedra (SiO₄). These structures can form chains, sheets, or three-dimensional networks.
- Các si-li-cát tạo nên cấu trúc của đất sét. (Silicates form the structure of clay.)
Variants and Related Words
- Silica (n): Silicon dioxide (SiO₂), a common compound found in nature (e.g., quartz, sand) and a fundamental component for forming silicates.
- Silicic acid (n): A general term for compounds containing silicon, oxygen, and hydrogen, which form silicate salts.
Synonyms
