Abstract

1 Scope This part of ISO 21068 gives definitions and specifies techniques for the preparation of samples for the chemical analysis of silicon-carbide-containing raw materials and refractory products including:

a) graphite brick containing silicon carbide;

b) silicon carbide brick (includes the bricks containing silicon nitride);

c) refractories containing carbon and/or silicon carbide mixed with clay;

d) refractories containing carbon and/or silicon carbide mixed with silica (and fused silica);

e) refractories containing carbon and/or silicon carbide mixed with high alumina material;

f) refractories containing carbon and/or silicon carbide mixed with magnesia (and dolomite);

g) refractories containing carbon and/or silicon carbide mixed with chrome mineral or magnesia-chrome materials;

h) refractories containing carbon and/or silicon carbide except those described in a) to g) above.
