Logas - Model 1A / 2B - Coatings - Datasheet

Logas comprises a granual material strongly bonded and formed into a weighed unit with high surface area to volume ratio to ensure maximum contact area with liquid metal. PURPOSE OF USE:- Logas is used for degassing of molten copper and copper based alloys. In copper and copper base alloys, dissolved hydrogen and cuprous oxide combine to form water vapor by steam reaction. The solubility of hydrogen in copper and its alloy melts reduces as the temperature falls until the gas attains the solid solubility. The hydrogen which is expelled from solution tends to combine with cuprous oxide levels are very low after deoxidation, hydrogen may still be problematic and it is preferable to reduce it to negligible proportions.
