Understanding Refractory Failure—A New Perspective
Certain startup fuel (i.e. #6 oil) may contain vanadium which could react with the silica and lime in the cement found in a cement-bonded-type refractory. When vanadium is present it can cause a chemical attack and surface failure or cause a complete refractory failure (no refractory present). Step 5 Review of Installation Procedures

Study of spent refractory waste recycling from metal
Feb 01 1999 · Refractories are classified as acidic basic or neutral based upon the anion to cation ratio. When the ratio is 1.5 1.0 the refractory is considered neutral as is the case with aluminum oxide (Al 2 O 3) where three anions (oxygen) and two cations (aluminum) yield a ratio of 1.5 1.0. When the ratio is greater than 1.5 1.0 the refractory is
