Boric acid acts as a flux and binder in medium-low temperature firing, promoting densification while lowering sintering temperature and shortening firing cycles.
Which castables suit phosphate binders?
STPP and SHMP are used in phosphate and aluminum phosphate bonded castables for mid-high temperature wear linings with high bonding strength and good thermal shock resistance.
Do you offer low-iron grades?
Yes. For Fe2O3-sensitive refractory applications we provide low-iron grades with test data and customization per your samples.
