Silicon nitride You can obtain this chemical reaction at 1300-1400degC by directly mixing elemental silicon with nitrogen. Here is the chemical formula 3Si(s) + 2N2(g) -Si3N4(s) This can be made with diimine. SiCl4(l) + 6NH3(g) -Si(NH)2(s) + 4NH4Cl(s) (at 0 degC) 3Si(NH)2(s) -Si3N4(s) +N2(g) + 3H2(g) (at 1000 degC) Alternativly,… Continue reading →
