Reduction of Oxygen Impurity in Multicrystalline Silicon

The graphite susceptor of the crucible can react with the crucible []: Experimental results [ 25 ] have shown that SiO gas is most likely to be rapidly formed when carbon and silica particles are in contact, and reaction ( 4 ) is favorable over the entire temperature range from 1500 to 2500 K.

Electrolysis of metal oxides in MgCl2 based molten salts

Pre-electrolysis of the molten salt was applied at 1.6 V to remove moisture and other redox-active impurities with the graphite crucible (or a graphite rod of 10 mm diameter in the alumina crucible) as the anode and a Mo wire (diameter: 2 mm) as the cathode.

Graphite Crucibles

Introduction Graphite Crucibles are refractory containers specially shaped for metallurgical operations. These are made of a mixture of Graphite, Refractory Clay, Grog and other additives. These crucibles are termed as clay bonded Graphite crucibles according to the

Mass production and industrial applications of graphene

INTRODUCTION Graphene has attracted attention worldwide and is considered a promising material for industrial applications. Before the exfoliation of graphene with Scotch tape was reported in 2004 [], several groups had exfoliated graphite to thin platelets [2, 3], and identified 'single-layer graphite' on noble metal surfaces as grown by chemical vapor deposition (CVD) [].

Clay Crucible Recipes : 8 Steps

Clay Crucible Recipes: This instructable is a few recipes for clay crucibles, getting them ready to melt metals and lots of pictures of things that didn't quite work out for me. But hey, it was fun.I have successfully melted Aluminum, Copper, Silver and various

Towards a functional and typological classification of crucibles

Gysel and Picon 1999). Graphite is a highly refractory mineral form of carbon with excellent thermal conductivity; in addi-tion, it acts in a similar way to inclusions of vegetable matter – both help produce reducing conditions within the crucible. Crucible form
