This my personal page on how to use MTA.  I am a masters research higher degree candidate.  My research involves collaboration with various engineers, particularly chemical and civil engineers, as well as cement technologists.

MTA is made by combining 80% Portland cement with 20% Bismuth Oxide.  From a manufacturing point of view, there is certainly more than just adding the two powders together as they have to ensure that the material is consistent and free from contaminants.

Bismuth oxide is chemically inert in the presence of Portland cement and therefore it is not expected to change the way Portland cement reacts in the form of MTA.

The information on Portland cement in the industrial setting is extensive and much of this information can be extrapolated over to the dental setting as there are many parallels.
