During melting nitrogen gas is used as inert gas to create the inert atmosphere around the molten matrix. Powder of alumina (Al 2 O 3) and graphite are used as reinforcement. 1% by weight of pure magnesium powder is used as wetting agent.
Silicon metal production Carbon and Graphite

Wettability of Aluminium with Aluminium Carbide (Graphite
Abstract. Graphite filters have previously been employed based on petrol coke. Wetting between molten aluminium and graphite is studied. Al 3 C 4 is formed at the interface between aluminium and graphite. In filtration of aluminium inclusions such as Al 3 C 4 formed in the hall electrolysis are removed. Wetting between aluminium and Al 3 C 4 (graphite) is determined in kinetic studies in the

Graphite / Carbon Joined to Metals with SBond®
SBond® active solders enable graphite bonding and the joining of other carbon or carbide based materials to each other and to most metals within the constraints of thermal expansion mismatch. SBond alloys have active elements such as titanium and cerium added to SnAg, SnInAg, and SnBi alloys to create a solder that can be reacted directly with the carbon surfaces prior to bonding using

Filtration of AluminiumExperiments, Wetting,and Modelling
In aluminium filtration,alumina is the most common filter material, even though alumina is not wetted by aluminium. Therefore we have investigated the use of alternative filter materials withimproved wetting. In the laboratory, SiC and graphite demonstrate good wetting bymolten aluminium.
