Slater Dust :

Slater Steels is a maker of special alloyed steels.

This dust is an industrial waste  material.

It comes from the anti-pollution system of the furnace.

Slater Dust has the following general analysis :

SiO2 5.39%
Fe2O3 50.3
CaO 12.12
MgO 3,27
ZnO 34.28

Total 100

Also small amounts of nickel, chromium,
molybdenum, cadmium, and manganese.

A possible substitution for 1% of this stuff
is as follows :

Dolomite .12
Whiting .11
Zinc oxide (calc.) .28
Silica .03
Red Iron Oxide .43
Total 1.00
