Abstract

The data presented in this article relate to the scientific article “Pyrolysis of a mixture of monosilane and alkanes in a compression reactor to produce nanodispersed silicon carbide” [1]. In the above article, a method is proposed for producing nanosized silicon carbide powder by compression in a cyclic process of a chemical reactor. Pyrolysis is initiated in mixtures of monosilane and hydrocarbon with argon. The article also presents the analysis data of the obtained product by X-ray diffraction and electron microscopy.

Data

The data set of this article contains information on the characteristics of silicon carbide nanopowders, obtained by the method of adiabatic compression in a chemical reactor [2]. Data on parameters inside the compression chamber, pressure and temperature are given. In papers [3e5], the importance of knowing the law of variation of these quantities during the compression-rarefaction cycle is indicated. The experimental data on the change in pressure inside the chamber during a period of three cycles of compression – rarefaction shows in Fig. 1. The black line is the experimental value obtained. The green line is the calculated dependence obtained in the approximation of the adiabatic ideal gas process, without taking into account the pressure drop during the opening of the exhaust valve. The experiment was performed using a crank mechanism. The calculation of the periodicity of cycles was obtained in the approximation of the harmonic law of motion of a piston with a frequency of 10 Hz. The temperature in the graph in Fig. 1 is marked with a blue line. The calculation was performed in the adiabatic compression approximation of a monatomic ideal gas according to T$Vg ¼ const and p$Vg ¼ const for initial data p ¼ 0.45 MPa, T ¼ 300 K
