    alloy
  2. rxn occurs when silver-based alloy is mixed with mercury
    amalgamation
  3. restorative material composed of silver-based alloy mixed with mercury
    dental amalgam
  4. irregularly shaped particles formed by shaving fine particles from an alloy ingot
    lathe-cut alloy
  5. alloy particles produced as small spheres
    spherical alloy
  6. mixture of lathe-cut and spherical alloys
    admixed alloy
  7. a chemical rxn btw tin in the silver-based alloy and mercury that caused corrosion in the amalgam
    Gamma-2 Phase
  8. oxidation affecting a thin layer of a metal at its surface. Not as destructive as corrosion
    Tarnish
  9. oxidation from interaction of two dissimilar metals in the presence of a solution containing electrolytes (such as saliva). it results in the breakdown of the amalgam
