Calcined aluminas AC34, AC44
Hard calcined aluminas contain more than 96% of -alumina providing very high temperature stability.
Calcined aluminas with two different soda contents are proposed: AC34 and AC44.
Silicon Nitrides N10 - N20
Nitrosil 10 - Nitrosil 20 are mainly used in alumina and silicon carbide based refractories.
This material has enhanced corrosion and thermal shock resistance.
Sialon N50
N50 is mainly used as a binder in the manufacture of silicon carbide monolithics refractories.
