One-step synthesis of in-situ carbon-containing calcium
· 1. Introduction. In recent decades castables which account for the greatest percentage of unshaped refractories have been extensively applied in the metallurgical cement and chemical industries among others owing to their quicker and cheaper installation and properties approaching those of shaped refractories .However castables suffer the same drawbacks such as low
