Graphite – Non-Wetting in Molten Zinc

Graphite is a fantastic refractory material. Graphite’s characteristics include a very low thermal coefficient of expansion, high-temperature tolerance, light weight, and relatively low cost. There are other materials that can be used to build zinc pumps such as MoW or Moly-Tungsten, but the MoW is very expensive and hard to work resulting a pump that is …
