The sintering step is most discussed in the powder metallurgy field. It reinforces the strength and shape of the metal powder during processing. Sintering allows loose particles to bond well under extreme surface tension created by heating. Extended heat exposure helps particles mix and mesh up with each other under their melting point. Unlike modern beliefs, sintering was used even in the old days. Clay pot making is a perfect example of this. Today, this method is applied to fabricate net-shape components using different materials, such as composites, metals, and ceramics. These parts are sought after in automobile, aeronautic, electronic-electrical, and medical industries for their conductivity, corrosion resistance, flexibility, mechanical and physical power, magnetic porousness, etc.
Which sintered material has gained immense popularity today? While every surface has its unique advantage, sintered ceramic has attracted enough attention for its multifaceted features. So, let’s delve into it.
The ceramic manufacturing process begins with choosing raw materials, sintering them, etc. Ceramics are inorganic, non-metal materials containing a mix of natural or artificial compounds. Previously, ceramic products were made of minerals, clay soil, and additives, which were exposed to high temperatures to obtain the desired endurance and stiffness. However, modern methods have helped make ceramics with oxides, nitrides, and carbides-like materials. Traditional components had limited applications, while sintered ceramics are used almost everywhere, including biomedical implants, engines, cutting tools, electronics, etc. They are used for their ability to resist abrasion, corrosion, and heat. Some applications benefit more from ceramic materials than steel.
Interestingly, sintered ceramic-based components are used in energy, medicine, and aerospace fields for their thermal, electrical, and tensile strength. Their pressure-bearing trait makes them suitable for engine parts and cutting tools. However, the most widely used ceramic product is a porous ceramic filter. There are multiple types, each solving an industrial purpose through its application.
- Sintered porous ceramic filters
Porous ceramic materials feature a vast network of closed pores after being shaped and sintered in heat. Their high density, chemical stability, and unique porous formation make them perfect for filtration in medical, pharma, energy, and environmental fields. The ceramic components can be available in various shapes, including honeycombs, tubes, discs, etc. Tubular filters offer better filtration due to the large filtration area. Whether you need something for your water treatment, oil separation, or acid and alkali solution, these tubes can hassle-free cater to your industrial needs. Their wear resistance, mechanical strength, corrosion-fighting abilities, and high-temperature tolerance levels enable them to efficiently handle corrosive fluids and even molten metals.
Another innovative ceramic design is honeycomb-style filters. These components are known for their diffusion capabilities, which give them sound-absorbing power. A good filter design like this can have high porosity, small pores, and enhanced mechanical qualities. Today, these filters are used in multiple places for sound insulation.
Thanks to the rising popularity of powder metallurgy methods like sintering, numerous ceramic components are available for industrial purposes at cost-effective rates. However, for quality assurance, ensure you buy them from a trusted store only. Check if the products meet international production standards.
