Definition

1. Noun (Chemistry):
   • Levigation: The process of grinding an insoluble substance into a fine powder, often while wet, and then allowing coarser particles to settle out from a suspension in order to separate and refine the finer particles.

Usage Examples

• Noun:
  • Trong phòng thí nghiệm, chúng tôi sử dụng phương pháp tách lắng để tinh chế bột. (In the laboratory, we use the levigation method to refine the powder.)
  • Tách lắng là một kỹ thuật quan trọng để phân loại hạt mịn. (Levigation is an important technique for classifying fine particles.)

Advanced Usage

• The term "tách lắng" is highly specialized and primarily used in scientific contexts, particularly in chemistry, materials science, and ceramics. It describes a specific physical separation process, not a general chemical reaction.

Variants and Related Words

• Lắng (v): to settle, to sediment.

  • Cặn sẽ lắng xuống đáy cốc. (The residue will settle to the bottom of the glass.)

• Ly tâm (v/n): to centrifuge / centrifugation.

  • Mẫu được tách bằng máy ly tâm. (The sample was separated using a centrifuge.)

Synonyms

• Levigation: The precise technical synonym.
• Sedimentation separation: A more descriptive term for the general process of separation by settling.

Related Terms and Processes

• Decantation: The process of pouring off a liquid, leaving sediment behind. This often follows the settling phase of tách lắng.
  • Sau khi tách lắng, phần nước trong được gạn đi. (After levigation/settling, the clear water is decanted.)
