What are glassy phosphates?

What are glassy phosphates?

• A. Small flaky particles of sodium polymetaphosphate
• B. Large sheets of glass-like material from sodium polymetaphosphate
• C. Small powdery particles of sodium polymetaphosphate
• D. Small broken glass-like particles of sodium polymetaphosphate

Answer: (D)

Glassy phosphates refer to an amorphous, glass-like phosphate material that is brittle and tends to break into small fragments. The term describes how the material fractures—like glass—producing small, irregular shards rather than flakes, sheets, or fine powder. That’s why small broken glass-like particles best fit the concept. Flaky structures imply flat, plate-like pieces; large sheets imply sheet form; powdery implies a very fine, fluffy material. None of those capture the glassy, brittle fragmentation pattern as well as the broken-glass fragments do.
