Carbon containing unburned bricks are made of magnesia or corundum as the main raw materials, with different proportions of graphite, resin as the binder, and various additives. They are formed under high pressure and heat treated at low temperature. According to the different raw materials used, there are two material series, magnesium carbon RMC and aluminum magnesium carbon AMC .
（1）镁碳砖（Carbonmag RMC）
主要原材料是镁和磷石墨.它具有极好的碱性炉渣耐药性，高温钢耐药性，耐热性电阻，脱皮性和导热性.}}}}在转化层，电炉和工作层中广泛用于carbor carlia carwia carwia carwia...。 Ao'an被用作开发和使用10年后的Rh真空炉.的工作衬里，它已变得非常成熟.
（2）Carbonmag AMC
主要的原材料是圆锥，镁和磷光石.它具有良好的炉渣耐药性，高温钢渗透力和耐侵蚀性，耐热性电阻和抗抗抗性，以及出色的高温机械柔韧性.，因此，它广泛用于棒壁和LADLE工作，并在Ladle壁和LADLE上使用。
