The experimental results are briefly summerized as follows;-
(1) TiO
2 in molten slag can be reduced with solid carbon and reducing gases, and the rate of reduction depends upon the chemical composition and other properties of the slag under the same conditions.
(2) In the presence of Ti
2O
3, slag is tinged with blue or bluish black.
(3) Two new minerals were found by the anther in the slag containing Ti
2O
3. The chemical composition of the one is (Cu, Mg, Fe) (Ti, Si)
4O
12 and the other probably 4CaO Ti
2O
3 2SiO
2.
(4) When the mixture of pig iron and slag containing titanium is melted in the reducing atmosphere mixed with nitrogengas, cyanonitride of titanium is formed in the neighbourhood of the contact surface of pig iron and slag.
