The difference between single crystal silicon and polycrystalline silicon is that when molten elemental silicon solidifies, silicon atoms are arranged in a diamond lattice into many crystal nuclei. If these crystal nuclei grow into crystal grains with the same crystal plane orientation, single crystal silicon is formed. If these crystal nuclei grow into crystal grains with different crystal plane orientations, polycrystalline silicon is formed. The difference between polycrystalline silicon and...

Standard glass melting furnaces are built with high-quality silicon fire-resistant mud. It is forbidden to use masonry kiln arches made of silica-based fire-resistant mud, all of which are configured with quartz fine powder and whose fracture-resistance is not satisfactory. When the inclined arch of the small furnace, the inserting of the flat arch, the side walls, the bottom, and the regenerator are built with silica bricks, appropriate expansion joints or related structures capable of...
Liquid-phase sintering refers to sintering produced by liquid phase. The liquid phase may be formed by the reaction of alkaline oxides such as Fe2O3, Na2O, TiO2, and K2O with Al2O3 and SiO2, resulting in a decrease in the high-temperature strength of the shell and cooling of the liquid phase. The particles are firmly connected to increase their residual strength. At 1200-1500°C, secondary morpholinization occurs in the shell, and alkaline oxides form liquid phases with Al2O3 and SiO2, resulting...
