The results of investigations into the organization of the synthesis of silicon carbide fibers in the gas phase using silicon powder, an energy additive of polytetrafluoroethylene (PTFE), and polyethylene (PE) powder by self-propagating high-temperature synthesis (SHS) are presented. Mixtures of the stoichiometric composition are used for experiments. Charge components are mixed in a drum with 3 L in volume with tungsten carbide balls for 30 min. The charge weight is 500 g. Experiments are performed in an SVS-30 industrial reactor. The combustion of the charge of the silicon + PTFE composition is accompanied by a rapid pressure rise from 0.5 to 4.0 MPa for a time shorter than 1 s and relatively rapid pressure drop to 1.5 MPa for 1.5 min. The combustion speed exceeds 50 cm/s. It is established that the combustion is accompanied by the spread of charge components, which is a consequence of the high process speed and intense gas liberation. A cottony light blue material, which consists of silicon carbide fibers 100–500 nm in thickness, is fabricated. The maximal reactor pressure during the combustion of the silicon + PTFE + PE composition reaches 3.1 MPa for 1 s and decreases to 1.5 MPa for 3 min. The combustion speed is about 40 cm/s. The entire accessory volume is filled by cottony blue-gray silicon carbide and SiC powder with equiaxial particles 0.5–3.0 μm in size combined into conglomerates. Silicon needlelike crystals are formed in a transient layer between the powder and silicon carbide fibers. The results of the experiments show the possibility of fabricating silicon carbide nanofibers in relatively large amounts under the combustion of exothermic mixtures.

提出了通过自蔓延高温合成（SHS）研究使用硅粉，聚四氟乙烯（PTFE）和聚乙烯（PE）粉末作为气相合成碳化硅纤维的组织的研究结果。 。化学计量组成的混合物用于实验。将装料成分在容量为3 L的鼓中与碳化钨球混合30分钟。装料重量为500克。实验在SVS-30工业反应器中进行。硅+ PTFE组合物的装料燃烧伴随着从0.5到4.0 MPa的快速压力上升，持续时间少于1 s，而相对迅速的压降在1.5 min的时间内下降到1.5 MPa。燃烧速度超过50 cm / s。已经确定，燃烧伴随着装料组分的扩散，这是高处理速度和强烈的气体释放的结果。制作了一种浅蓝色的棉质材料，该材料由厚度为100-500 nm的碳化硅纤维组成。硅+ PTFE + PE组合物燃烧过程中的最大反应器压力在1 s内达到3.1 MPa，并在3分钟内降至1.5 MPa。燃烧速度为约40cm / s。整个附件体积由棉质蓝灰色碳化硅和SiC粉填充，等轴尺寸为0.5-3.0μm的颗粒合并成团块。在粉末和碳化硅纤维之间的过渡层中形成了硅针状晶体。
