Canada is one of the top graphite-producing countries in the world with over 40,000 metric tons of the mineral produced in 2018. Interest in graphite has been growing recently due to Tesla's announcement that they will be sourcing ingredients for their batteries (like lithium, cobalt, and graphite) from North America.
Cast irons are known to be easy to shape by sand casting due to their high eutectic fraction. Despite this fact, together with cost benefits, obtaining good quality castings is not an easy task, although it depends on the level of defects allowed in each case. Casting defects are here reviewed and classified into three classes according to …
