  • Slow fade inocculant and a process for the inocculation of melted cast iron
    Patent number: 4292075
    Abstract: A slow fade cast iron inocculant is made up of(a) a silicon-containing matrix of iron silicon alloys and having a crystal structure,(b) compounds, present in the matrix crystal structure, of high-melting point calcium aluminum silicates, generally in the form CaO.Al.sub.2 O.sub.3.2SiO.sub.2 +Al.sub.2 O.sub.3.2SiO.sub.2, and(c) a dicalcium aluminum silicate material with up to 20% by weight of silicon carbide and 10% by weight of calcium carbide.The relation between the matrix and the high-melting point calcium aluminum silicates to the dicalcium silicate material is about 1 to 0.05-0.2. The amount of high-melting point calcium aluminum silicates in the matrix is 5 to 30% by weight and, more specially 8 to 15% by weight.
