Electrocal, thermal, thermoelectric and related properties of magnesium silicide semiconductor prepared from rice husk

Characteristics of a Pin–Fin Structure Thermoelectric Uni-Leg Device Using a Commercial n-Type Mg2Si Source

“…On the other hand, magnesium silicide (Mg 2 Si) has been identified as a promising advanced TE material, operating at temperatures ranging from 500 K to 800 K. Its properties, such as being an environmentally benign material, the abundance of its constituent elements in the Earth's crust, and the nontoxicity of its processing by-products, make Mg 2 Si an attractive material for TE generation. [4][5][6][7] Moreover, the dimensionless figure of merit, ZT, characterizing the efficiency of a TE material, for n-type Mg 2 Si has already reached $1.0 at 873 K. 8 Although a large number of studies have been done on the TE characteristics of Mg 2 Si, [9][10][11][12][13][14] the output characteristics of Mg 2 Si TE elements and modules have not been sufficiently investigated.…”

The quantitative estimation of silica in rice husk ash by titrimetric method: A case study for uncertainty calculation

“…This silica has been shown to be a good material for the synthesis of pure silicon, silicon nitride, silicon carbide, magnesium silicide etc [2][3][4][5]. Utilization of rice husk as a resource of silica is depending on the percentage of silica in raw material and cost effective process for removal of impurities.…”

Rice Husk and Its Applications: Review

“…The amorphous SiO 2 was thus reduced to form silicon according to the following reaction (Bose et al, 1993) SiO 2 + 2Mg = Si + 2MgO + SiO 2 (unreacted)…”
