摘　　要：太阳能单晶硅炉需要为单晶硅晶体生长提供稳定的高温热场环境(约1500℃),既需要耐高温保温材料保证热场的温度梯度,又需要耐高温结构材料支撑长晶坩埚并均匀传输热量。炭/炭复合材料本身具有优异的耐高温性能(真空或惰性气体条件>2800℃),同时低密度炭/炭复合材料具有优异的高温保温性能,高密度炭/炭复合材料具有优异的力学性能和传热性能。立足太阳能单晶硅长晶炉的产业应用需求,对炭/炭复合材料的性能、应用、分类和制备方法及表面处理进行了系统性介绍,希望对大尺寸晶体生长炉用炭/炭复合材料的制备和应用提供一些借鉴。In a solar monocrystalline furnace,a stable high-temperature thermal field(approx.1500℃)needs to be provided for the growth of monocrystalline silicon crystals.High-temperature resistant insulation materials are required to ensure the temperature gradient of the thermal field,and to support the long crystal crucible and transfer the heat uniformly.Carbon/carbon composites have excellent high-temperature resistance(vacuum or inert gas conditions>2800℃),while low-density carbon/carbon composites have excellent high-temperature insulation properties,and high-density carbon/carbon composites have excellent mechanical properties and heat transfer properties.The properties,applications,classification,and preparation methods of carbon/carbon composites and surface treatment are systematically introduced,based on the industrial application requirements of solar monocrystalline silicon long crystal furnaces.It is hoped to provide some references for the preparation and application of carbon/carbon composite materials for large-scale crystal growth furnaces.
