for sintering of Spray-1 Si substrates. For the other type of sprayed Si substrates 3% (weight) of Al powder was mixedwiththeSipowder-basedfeedstockpriorthespraying (Spray 2 substrates). In case of the casting process, which was carried out using a VGF furnace at SINTEF, Si powders with PSD values up to 150mm have been used. The silicon powder-
Alibaba.com offers 412 mould heating furnace products. About 23% of these are industrial furnace, 5% are laboratory heating equipments. A wide variety of mould heating furnace options are available to you, such as resistance furnace, induction furnace.
graphite crucible A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.
I. necessary skills for the use of vacuum sintering furnace. Vacuum sintering furnace is after vacuum filling hydrogen protection condition, by using the principle of intermediate frequency induction heating, the high temperature of tungsten crucible in the winding, by heat conduction to work on, suitable for scientific research, military units
Experts on hot zone of single crystal furnace & polycrystalline furnace: Since the division was established in 2005, we is continuing to improve the processing technology, committe to match single crystal furnace & polycrystalline furnace graphite hot zone of Hanhong and other brands.
In the present work, we studied the effect of the sintering treatment on crystallite size, hydrogen bond structure and morphology of the silicon powders from silane thermal decomposition with the aim of re-utilizing the by-product fine powders during the polysilicon FBR-CVD production.
The sintering molybdenum crucible is mainly used for the production of large molybdenum crucible. Compress the molybdenum powder in the mould by the isostatic pressing process, sintering under high temperature. And then polish the outer surface and inner surface of molybdenum crucible through mechanical processing. Stamping molybdenum crucible
2013725Whereby, the combined graphite tube of the present invention may be utilized in silicon smelting, and may be coupled to an enough length of graphite tube depending on requirements or derive a graphite crucible, capable of improving silicon smelting efficiency.

In selective laser sintering, an entire layer is placed on the platform and the part powder is selectively laser fused while powder in the non-forming areas remains in the loose state. However in the present method, both the part powder and the mould powder remain in the loose state before entering a conventional sintering furnace.
