Silicon carbide is a hard and durable material with excellent thermal conductivity properties, which makes it suitable for high-performance applications like electronics, automotive and aerospace. Furthermore, its corrosion and oxidation resistance makes it a top pick.

Alumina is an extremely flexible material used in numerous industrial applications ranging from abrasives to ceramic products. Aside from being strong and chemically stable, alumina also boasts good thermal conductivity properties as well as production methods including hot pressing and pressureless sintering; making it one of the more widely available refractory materials.

As its name implies, alumina is composed of silicon and aluminum – an incredible combination that makes for a very versatile and affordable material. Due to its low vapor point and melting temperature, alumina is widely used in abrasives, ceramics, electronics as well as its strong wear resistance properties which also make it popular among metallurgy, automotive and aerospace industries.

Alumina is frequently utilized in the abrasive industry as a blasting abrasive, as its sharp, pointed edges enable it to cut through tough materials such as stone, glass and marble with ease. Furthermore, its ability to withstand multiple blast cycles makes alumina one of the most cost-effective industrial abrasives available; in addition, etching works well and can prepare surfaces for coating applications.

Heat Resistance

Silicon carbide is one of the hardest materials on Earth – second only to diamond and boron carbide – giving it superior wear resistance. Furthermore, its heat resistance allows it to withstand temperatures as high as 1600degC without losing strength or its ability to transfer heat, making it an ideal material for applications requiring high levels of mechanical stress.

Alumina silicon carbide can be formed into various shapes and sizes, making it an extremely flexible construction material. It is often utilized for use in metallurgical applications like secondary tuyere bricks for aluminum melting furnaces or waste incinerators; additionally it is often found as substrate material for radar chips as it has excellent heat dissipation properties and high-temperature resistance.

The present invention describes a new alumina-silicon carbide heat-resistant composite sintered body with superior resistance to oxidation and sintering, obtained by molding a mixture of alumina powder and silicon carbide powder, grinding these raw materials into fine particles, grading the grains and powders according to predetermined percentages, adding bonding clay as required, molding green bodies until ready for firing, then molding drying and firing the green bodies until an alumina-silicon carbide heat-resistant refractory is obtained. This new alumina-silicon carbide heat-resistant sintered body boasts strong resistances against both oxidation and sintering while providing high resistances against cracking deformation at higher temperatures as well as good resistances against cracking deformation at higher temperatures.

Motståndskraft mot slitage

Alumina ceramics boast an exceptional Mohs hardness rating of 9, making them extremely tough and wear resistant – properties which make them the go-to choice for applications that endure high abrasive forces, such as bearings and seals.

Silicon carbide sets the bar high when it comes to hardness and durability. As one of the hardest materials available, it can withstand extremely high temperatures without losing strength or hardness – perfect for environments with rapid temperature shifts that demand constant monitoring. Plus, its low coefficient of thermal expansion makes it suitable for environments experiencing rapid climate fluctuations.

Silicon carbide stands up well against abrasion, corrosion and oxidation; furthermore it demonstrates remarkable chemical inertness – an ability that makes it an indispensable component in numerous industries.

Alumina enhanced by bonding to graphene boasts impressive wear resistance properties. A recent study concluded that adding graphene to an alumina/silicon carbide nanocomposites significantly improves their performance during sliding tests by decreasing wear transition behavior induced by abrasion-induce wear transition, as well as providing self-lubrication properties and decreasing grain pullout during sliding test runs.

Blasch offers several silicon carbide compositions designed for excellent erosion and corrosion resistance. Reaction Bonded Silicon Carbide (RBSC) is particularly favored when applications require strong impact resistance; we offer it in cone and sleeve shapes.
