For this purpose, Silicon Carbide (SiC), Titanium (Ti), graphite (C) and aluminum (Al) powders with molar ratios of 3Ti:1.2SiC:0.8C, 3Ti:1.2SiC: 0.8C:0.1Al and 3Ti:1.2CiC:0.8C:0.3Al were mixed by a planetary mill under an argon atmosphere for 5h. The resulting mixture was formed with a press and subjected to arc melting at 1, 3, 5, and 10s. In samples containing Al additive, the purity of Ti₃SiC₂ increases with increasing arc melting setting time up to 5s, and the purity decreases with increasing the arc time. The best result was obtained in the sample 3Ti:1.2SiC:0.8C:0.1Al containing 83.6 wt% of Ti₃SiC₂, which was obtained during the 5s arc melting. https://macs.semnan.ac.ir/article_6926_9b8b50fb590c590ffbf1295ce92258dc.pdf
