[Consistency of zinc oxide-eugenol impression materials]. Manufacture: most active ZnO powders are those formed from zinc salts like zinc hydroxide, zinc carbonate by heating at 3000 degree Celsius. 150g + 60g. The setting reaction is between zinc oxide and the eugenol that are the two main ingredients of this dental cement. The oil, which can also be vegetable in nature, helps to reduce the potential irritant action of eugenol.
