Sialon ULTRA™ is the new standard for the molten aluminium industry with a 30% higher impact fracture toughness than conventional Silicon Nitrides. All our products are polished to improve even more its excellent non-wetting properties.
XICAR® sintered silicon carbide is highly durable and performs exceptionally well in extreme high-temperature applications up to 1,900°C. It is highly resistant to chemical corrosion, making it an excellent choice for challenging applications in various industries.
Our SSiC thermocouple protection tubes are highly durable and perfect for harsh industrial environments. They resist corrosion and abrasion, can withstand high temperatures, and meet high standards of performance and reliability.
Get our premium XICAR® silicon carbide crucibles for high-temp processes. They meet industry standards and offer unbeatable quality, durability and performance.
XICAR™ Sintered silicon carbide provides a unique combination of physical properties, including high mechanical strength, toughness, excellent thermal shock resistance and resistance to corrosion. As a result, it is ideal for applications involving exposure to high-temperature liquids such as alloy melts and exposure to hot gases, with applications in mineral and chemical processing kilns and furnaces.
Sialon II ™ ladles (silicon nitride) are strong ladles for high pressure die casting machines and the best choice when it comes to non-wetting and mechanical strength properties.
