To Choose the Right Sand Additive, Understand Composition ...

Iron oxides additives have been used for many years and are typically some form of red iron oxide (hematite, Fe 2 O 3) and black iron oxide (magnetite, Fe 3 O 4), or sometimes a blend of the two. They act as a flux to promote softening of the sand, which can absorb more thermal stress before a crack occurs in the core or mold.

Low-iron glass - Wikipedia

Low-iron glass is made from low-iron silica sand. In the United States, the primary sources for such sand are in Wisconsin. Fallingwater, a house designed by Frank Lloyd Wright and built in 1939, was one of the first houses to use low-iron glass for windows. Low iron glass is widely used in solar panels.

Foundry sand testing - Wikipedia

Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a pattern.In a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.

Testing 1-2-3: Eliminating Veining Defects Modern Casting

Jul 01, 2014  The linear expansion of bonded silica sand causes the volume of sand to increase sharply until 1,063F (573C), where it changes phase from alpha quartz to beta quartz. Upon further heating, the sand loses its volume due to loss of binder volume and softening and rearrangement at the surface of the sand grains.
