High Alumina Refractory

Refractories must be picked by conditions they will confront. A few applications require unique stubborn materials. Zirconia is utilized when the material must withstand greatly high temperatures. Silicon carbide and carbon (graphite) are two other hard-headed materials utilized as a part of some exceptionally extreme temperature conditions, yet they can't be utilized as a part of contact with oxygen, as they will oxidize and burn.
