Silicon carbide tube properties

• High strength: The main component of silicon carbide tube is silicon carbide, which is a very hard substance, so the silicon carbide tube itself has high strength.
• High hardness: The Mohs hardness of silicon carbide reaches 9.5, second only to the world’s hardest diamond (10), so the silicon carbide tube is also very hard.
• Good wear resistance: Since silicon carbide has very good wear resistance, it also has good wear resistance.
• High temperature resistance: it can withstand very high temperatures without damage, which makes it very suitable for use in high temperature environments.
• Corrosion resistance: Silicon carbide tube has good corrosion resistance and can resist the erosion of many chemicals.
• Good heat and shock resistance: it can remain stable under temperature changes and vibrations, and is not easy to break or damage.
• High thermal conductivity: Silicon carbide tube has good thermal conductivity and can quickly transfer heat, which is very important for applications that require rapid heating or cooling.
• Good oxidation resistance: it can also maintain its performance in an oxidizing environment, which makes it very useful in many industrial applications.

Production process

Raw material selection

• The main raw materials are high-purity silicon carbide powder and binder

Hot pressing process

• After mixing the raw materials, add water in a certain proportion to make a solid blank, then form it through a mold and enter the hot pressing device for hot pressing
  The hot pressing temperature is 2200-2300℃℃, the pressure is 20-30MPa, and the hot pressing time is usually more than 2 hours

Post-processing process

• The blank after hot pressing is dried, degreased, polished and other processing procedures to finally form a finished product
• The drying time is 12-24 hours, and the drying temperature is generally between 120-150℃

Static pressure production technology and process

• Static pressure, as a key process in processing technology, can effectively improve the density and strength of the product
• Equipment operation: Static pressure equipment is a high-precision equipment that requires strict equipment debugging, processing process control and other operations to ensure the stability and consistency of product quality
• Static pressure parameter control: During the static pressing process, it is necessary to accurately control parameters such as pressure, temperature, and holding time to achieve the ideal effect
• Mold making: The design and production of the mold have an important influence on the effect of static pressing processing

Application scenarios of silicon carbide tubes

• Solar inverters
• New energy vehicle chargers
• Switching power supplies
