Dear Friends ,
I have taken up a work on analysing a sand which is the by product of a clay industry. I was thinking if it could be modified as a foundry sand.
Table . Foundry sand sample chemical oxide composition, %. (1)
Constituent Value (%)
SiO2 87.91
Al2O3 4.70
Fe2O3 0.94
CaO 0.14
MgO 0.30
SO3 0.09
Na2O 0.19
K2O 0.25
TiO2 0.15
P2O5 0.00
Mn2O3 0.02
SrO 0.03
LOI 5.15 (0.45 to 9.47)(1)
2.1 - 12.1(2)
TOTAL 99.87
