摘要:
以内蒙古煤矸石为主要原料,采用高温还原氮化方法合成塞隆材料,研究了碳含量、煅烧温度以及保温时间对煤矸石碳热还原氮化反应程度和反应产物的影响.通过试样烧失率的计算,以及采用XRD和SEM 分析,研究煤矸石在碳热氮化反应过程中得到β′-SiAlON相、X相及O′-SiAlON相的反应条件.研究表明:反应过程中,随着还原剂碳的增加,试样的烧失率逐渐增大,而保温时间对烧失率和反应生成物的影响不大;在煤矸石碳热还原氮化反应中,反应生成物X相均较少,最高只有12.88%,反应条件应为反应温度高于1 420 ℃,含碳量大于10%;还原剂碳含量和温度对生成β′-SiAlON相、O′-SiAlON相有显著影响,还原剂碳的合适加入量为10%~16%;当反应温度高于1 420℃×6h时,有利于β′-SiAlON相、O′-SiAlON相的生成.在1 420℃、含碳量14%时,生成主晶相β′-SiAlON相占57.21%;在1 350℃,Z=0.4时,碳含量为16%时,生成O′-SiAlON相占23.80%.
Abstract:
Using Inner Mongolia coal gangue as the main raw material, different SiAlON products were synthesized by high temperature carbothermal reduction- nitridation and some reactive conditions such as the content of carbon, calcining temperature and keeping time influencing on extent of reaction and reactive products were researched. By calculating the lossrate of ignition of samples, using XRD and SEM analysis, the reactive conditions getting β′-SiAlON, X-phase and O′-SiAlON phase by carbothermal reduction- nitridation reaction of coal gangue were studied. The results show that the loss rate of ignition of specimens rises with carbon reducer increasing and keeping time has a little influence on the loss rate of ignition of specimens. During the carbothermal reduction and nitridation reaction of coal gangue, the yield of X phase is low and the highest yield is only 12.88%under the reactive conditions of temperature higher than 1 420℃and carbon reducer above 10%.The content of carbon reducer and reactive temperature greatly influences the yield of β′-SiAlON and O′-SiAlON phase. The appropriate addition of reducer carbon is 10%~16%, and the reaction temperature over 1 420℃ and keeping time of 6h are beneficial to the formation of X phase, β′-SiAlON and O′-SiAlON. Under the reactive conditions of temperature 1 420℃and carbon reducer 14%, the yield of β′-SiAlON phase is 57.21%. Under the reactive conditions of temperature 1 350 ℃, Z=0.4and carbon reducer 16%, the yield of O′-SiAlON phase is 23.80%.
