C.  aEffect of NaCl and MgCO3 additions on the crystalline phases formation during open-pore glass processing.  c1999  aIn this work the effect of the addition of NaCl and MgCO3 salts in the crystalization of soda-lime-silica glass during conventional sintering is evaluated. These salts were added to the glass powder as non-sinterable phase to be removed after the heating cycle.  aEnzimas  aSoda-lime-silica  aX-ray1 aASSIS, O. B. G.1 aGOY, R.
