It is shown that the modern method of self-propagating high-temperature synthesis (SHS), which is also called combustion Synthesis, is more cost-effective and attractive for producing a powder composition of AlN-SiC, compared to other traditional more complex and energy-intensive methods. The well-known varieties of using the SHS method for obtaining AlN-SiC, their advantages and disadvantages are listed. The possibility of preparation of ceramic nitride-carbide powder composition AlN–SiC by the method of azide SHS during the combustion of powders mixtures of Al, Si, C, sodium azide NaN3and halide salt (NH4)2SiF6is studied using a thermodynamic calculation and an experimental study of the temperature and composition of combustion products.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130206574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

YAG:Nd3+ laser ($lambda=1064 mathrm{nm}, tau_{mathrm{i}}=14 mathrm{ns}$) was used as a source of initiation. The basic elements of the data-acquisition equipment were a polychromator and a streak camera. They were used for a luminescence spectrum scanning in time. Under the influence of a laser impulse, one was recorded the luminescence with its intensity falling down in time of ∼ 60 ns. The state of a maximum of the luminescence spectrum scanning depends on the energy density of a laser radiation $H$. At increasing $H$, the state of a maximum migrates from the visible to the ultraviolet area up to the value $lambda=420 mathrm{nm}$. This luminescence is connected with the NO2. radicals which are formed during the influence of a laser impulse and variously excited. The luminescence of products of an explosion is observed in a microsecond time interval and has the thermal nature. The luminescence temperature is $T=3500 mathrm{K}$.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134235302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially, the influence of the anode activity (various high-current anode modes) on the properties of vacuum arc plasma has been studied. The vacuum arcs have been investigated under typical switching conditions - ignition by CuCr contact separation during the AC current flow at several kA magnitude. High-speed cinematography was used for observation of arc dynamics and characterization of the anode activity. Optical emission spectroscopy (imaging, high-speed) has been applied for determination of temporal dynamics of copper spectral lines from various plasma species – atoms, ions and electrons during the active phase, as well as for determination of plasma temperature. Several methods have been used for quantitative characterization of the anode surface temperature: NIR spectroscopy and high-speed camera techniques enhanced by narrow-band filters. Broad band absorption spectroscopy is a suitable technique for determination of the vapour density close to the current zero crossing and in the early post-arc phase. The corresponding values for the Cr ground state density are presented.","PeriodicalId":190249,"journal":{"name":"2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132180075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
