Translation Traps (for Russian speakers)
- Не переводите как 'силикат магния' в бытовом контексте — это исключительно технический термин.

Common Mistakes
- Pronouncing 'silicate' with a hard 'c' (/sɪlɪˈkeɪt/ is incorrect; it's /ˈsɪlɪkət/ or /ˈsɪlɪkeɪt/).
- Using as a countable noun (e.g., 'a magnesium silicate' is rare; usually uncountable).
