摘要

当页岩燃烧产生的废粘土在250℃下烧制时，有机质的分解导致陶瓷样品中释放出H2、CO、SO3和CO2。在350-550℃时，氧化剂(氧)和中性气体(氮)的含量明显减少。在550-750℃时，它们的含量没有急剧下降。在750 ~ 1000℃时，下降幅度不大。在1000℃时，主要形成CO。在1050°C时，烧制的样品几乎不含有机化合物。随着机械强度的增加，形成更复杂的化合物(钙长石，透辉石)。

Phase Composition of Interstitial Clay and Gas Emissions on Heat Treatment

When interstitial clay, which is the waste from shale combustion, is fired at 250°C, the decomposition of organic matter results in the emission of H₂, CO, SO₃, and CO₂ from the ceramic samples. At 350–550°C, the content of oxidant (oxygen) and neutral gas (nitrogen) is markedly less. At 550–750°C, no sharp decrease in their content is observed. At 750–1000°C, the decrease is slight. At 1000°C, mainly CO is formed. At 1050°C, the fired sample contains practically no organic compounds. More complex compounds (anorthite, diopside) are formed, with increase in the mechanical strength.
