The use of graphite in the refractory industry
Refractory products are nonmetallic ceramic materials (may contain metals) that have a certain refractorinessa pyrometric cone equivalent of ≥ 1 500 C. OR Refractories are products which are installed whenever high temperature ( 6002 000 C) exists. Refractory materials are based on 6 oxides Al 2 O 3 SiO 2 MgO CaO Cr 2 O 3 ZrO 2
