Main features and advantages of HEJING quartz crucible
1.The ceramic body obtained by direct solidification of quartz ceramic slurry in the mold has the advantages of uniform crucible structure, high density and low porosity.
2.Using the mould of unique material, the size consistency of the crucible is good, the taper of the side wall is moderate, which is conducive to the reasonable distribution of heat field and the long crystal of silicon in the ingot casting process.
3.The unique surface structure and uniform roughness of the inner wall of the crucible are especially suitable for the spraying of silicon nitride coating, which has strong adhesion and is not easy to peel off.
4.The forming process has high strength and has incomparable advantage in reproduction of large size crucible.

Various  of high purity, high efficiency, no spray quartz crucible products.
Note:Other quartz crucible can be produced according to customer's requirment

Products quality

1.HEJING quartz crucible is managed and controlled in accordance with ISO9001 quality management system.
2.
Raw material control: Strictly control the quality of incoming raw materials, inspect and accept each batch of raw materials to ensure that incoming raw materials meet the requirements.
3.Production process:Strictly follow the production operation procedures, adopt special material mold, high strength, and adopt continuous firing tunnel kiln and drying kiln equipment, to ensure uniform size and stable quality of products.
4.Quality inspection:Nondestructive testing methods, such as lamp inspection, were used to ensure that there were no defects in the crucible. The inspection report of each crucible was kept by the quality inspection department, and the key data records were kept and used to improve the production process.
5.Products serial number:Ensure the traceability of product quality.
6.Products packing:Crucible products qualified by inspection shall be cleaned, dried and packed to ensure the cleanliness of all crucible.

4.The crucible process can be adjusted according to the needs of customers, so that customers can achieve the maximum benefit.

Matters needing attention during using quartz ceramic crucible

Dear clients:

Thank you very much for choosing HEXING products, because the quartz ceramic crucible is extremely demanding in its use conditions, there are extremely strict requirements for crucible.In order to make our products create better value for you, please pay attention to the following points:
1. The packing case is a square carton, intact and undamaged. It has not been soaked.
2.No red on quakeproof mark
3.When handling quartz crucible, excessive force or collision should be avoided
4.Please open the package in use after wearing white gloves, handle gently, so as not to cause pollution and damage to the crucible
5.crucible storage warehouse location must be kept dry and ventilated.
6. Please strictly comply with the operating process during using the crucible.
Dear friend, if you have any other requirment and good suggestion , please feel free to contact with us, we will try our best to provide best support to you.
Thank you very much, wish we can have a good corperation!
