Applications:
Application A: Polycrystalline silicon Reduction Furnace
Polycrystalline silicon reduction furnace, also commonly referred to as "polysilicon furnace", is a type of energy-saving furnace equipment generally used in the production of polysilicon products. In contrast to single-crystal silicon and amorphous silicon, polysilicon has the characteristics of better optical, electrical and thermal properties, making it an ideal component for solar cells, semiconductors and other devices. The furnace works by reducing silicons from mineral raw materials to produce polysilicon products.
Application B: Low Pressure Casting
Low pressure casting is a metal casting process in which liquid metal is injected into the mold at atmospheric pressure. Compared with traditional sand casting, the pressure casting process produces castings with improved dimensional accuracy, surface finish and mechanical performance. It is widely used in various industries such as automobile, aerospace, mining and military industry. Low pressure casting is usually done on aluminum and magnesium alloys, although some steel and copper alloys can also be processed by this method.
Application C: Papermaking
Papermaking is the process of producing paper from various raw materials including wood and cloth fiber. This process usually involves a combination of milling, screening and drying processes. Papermaking is used in a variety of industries, ranging from printing to packaging, and can be used to manufacture a variety of end products, including newsprint, writing paper, office stationery, packaging materials and other cardboard products.
Application D: Bearings
Bearings are used in a variety of mechanical applications to reduce friction and enable smoother movement of machinery. Common bearing types include ball bearings, tapered roller bearings, cylindrical roller bearings, spherical bearings, roller thrust bearings, and journal bearings. They are used in machines ranging from automobiles to industrial machinery to agricultural equipment. Bearing selection is based on several factors, including load, speed, operating temperature, and operating environment.

Packing and Shipping:
The packaging and shipping of Silicon Nitride Ceramics should be done with great care as the product is made of a fragile material. The product should be placed in a sealed box and surrounded by a layer of bubble wrap to protect it from any impacts during transit. The box should also be labeled clearly with the product name, “Silicon Nitride Ceramics”, and any other relevant information. It should also be shipped in an appropriate temperature-controlled environment to ensure that the product does not suffer from extreme temperatures.
