Which one of the following is not an objective of trituration ?
Correct answer: B. Keep the amount of gamma-1 or gamma-2 matrix crystals to maximum
- A. Remove oxides from powder particle surface
- B. Keep the amount of gamma-1 or gamma-2 matrix crystals to maximum
- C. Pulverize pelletes into particles to aid in attack by mercury
- D. Achieve a workable mass of amalgam in minimum time
Explanation
Trituration should produce a workable amalgam and expose alloy surfaces for mercury reaction, while reducing undesirable phases such as gamma-2. Keeping gamma-1 or gamma-2 crystals to a maximum is therefore not an objective, especially for gamma-2.
