Abstract
Official abstract text for this publication.
Puncturing of plastic bags containing polysilicon chunks during transport thereof and reduction of fines generation are minimized by use of a transport vessel containing at least two plastic bags containing polysilicon chunks with a packing density of greater than or equal to 500 kg/m 3 .
First claim
Opening claim text (preview).
The invention claimed is: 1. A transport vessel comprising at least two plastic bags each with polycrystalline silicon chunks within, the transport vessel having a base, and having a packing density of greater than or equal to 650 kg/m 3 and less than or equal to 950 kg/m 3 , wherein the plastic bags in the transport are vessel arranged horizontally and overlaying such that an elongated side of the plastic bags is parallel to a plane of the transport vessel base, and wherein the ratio of the total volume of each plastic bag to the volume of chunks present therein is 2.4 to 3.0. 2. The transport vessel of claim 1 , having a packing density of greater than 800 kg/m 3 and less than 950 kg/m 3 . 3. The transport vessel of claim 1 , wherein a residual volume present in the transport vessel is filled to an extent of more than 70% by inserts made of foam or shape-forming elements of polyurethane, polyester, or expandable polystyrene. 4. The transport vessel of claim 1 , wherein the plastic bags at least partially overlap. 5. The transport vessel of claim 1 , wherein inserts are located between overlaying plastic bags.
