20/3/2019· Preparation Silicon tetrachloride is prepared by heating either silicon or silicon carbide with chloride. Si (s) + 2 Cl 2 (g) ——> SiCl 4 (l) SiC(s) + 4 Cl 2 (g) ——-> SiCl 4 (l) + CCl 4 (l) Properties 1) It is a volatile liquid , b.p. 330.57 K. 2) Hydrolysis Hydrolysis of SiCl 4 gives silicic acid , Si(OH) 4 which upon further heating undergoes partial dehydration to give silica gel.
The mechanism of thermal diffusion in silicon carbide is quite complex as the crystal has two sublattices (silicon and carbon). Previously, Gao et al. and Lebedev [ 20 , 28 ] studied boron diffusion on 6 H -SiC in the temperature range between 2000 and 2200°C and have demonstrated that there are two types of boron solubility depending on the position of boron atoms in the carbon or silicon
Experimental data on diffusion of erbium and vanadium in porous and nonporous silicon carbide at 1700 and 2200°C have been used for modelling diffusion in porous SiC. It is shown that the consideration of pore structure modifiion under annealing via vacancy redistribution allows for satisfactory description of dopant diffusion. As expected, important contribution to the diffusion in

Silicon is a semiconductor, readily either donating or sharing its four outer electrons, allowing for many different forms of chemical bonding. Even though it is, similar to carbon, a relatively inert element, silicon still reacts with halogens and dilute alkalis, but most acids (except for some hyper-reactive coinations of nitric acid and hydrofluoric acid) have no known effect on it.
The complete hydrolysis of SiCl 4 yields SiO 2, which has a very stable three-dimensional structure. The fundamental research of F.S.Kipping on the hydrolysis of alkyl substituted chlorosilanes led to the discovery of long-chain polymers called silicones.
