Tungsten carbide (TgC) powders are used in various industries such as automotive, aerospace, and jewelry making due to their excellent wear-resistance properties. On the other hand, ceramic powders are commonly used in industry for their high strength-to-weight ratio, thermal stability, and chemical resistance.
(what are tgr differences between metal and ceramic powders for processing)
One of the primary differences between TgC powder and ceramic powder is their composition. TgC powders contain at least 70% tungsten, while ceramic powders typically contain a higher percentage of carbon, which results in a stronger material. Additionally, TgC powders have a harder surface than ceramic powders, making them more suitable for applications where a hard surface is required.
Another difference is in their properties. TgC powders have excellent wear-resistance properties, making them ideal for use in abrasive applications such as grinding and cutting. They also have good thermal stability, which means that they can withstand high temperatures without losing their properties. However, TgC powders have a lower melting point than ceramic powders, which makes them less suitable for applications where heat transfer is critical.
Ceramic powders on the other hand have higher thermal stability, meaning that they can withstand high temperatures without losing their properties. This makes them ideal for applications where heat transfer is critical, such as in the production of ceramics such as glass and pottery. They also have excellent chemical resistance, making them resistant to chemicals and solvents.
In terms of processing, TgC powders tend to be harder and more brittle than ceramic powders, which makes them more suitable for applications where a hard surface is required. They also require less moisture during processing than ceramic powders, which makes them more convenient to handle and store.
(what are tgr differences between metal and ceramic powders for processing)
In conclusion, both TgC powder and ceramic powder have unique properties that make them suitable for different applications. TgC powders have excellent wear-resistance properties, high thermal stability, and better chemical resistance, making them ideal for use in abrasive applications. However, they also have a lower melting point and require less moisture during processing than ceramic powders. Ceramic powders on the other hand have higher thermal stability, chemical resistance, and are easy to process. The choice between TgC powder and ceramic powder will depend on the specific requirements of the application.
