MORGAN ADVANCED MATERIALS: Nitride-Bonded Silicon Carbide Kiln Furniture
Morgan Advanced Materials recently launched a range of kiln furniture made from a new nitride-bonded silicon carbide material that is reportedly suitable for use at temperatures of up to 1,500°C (2,732°F). The material, known as Halsic-N, reportedly combines the properties of proven materials such as silicon carbide (SiC) and silicon nitride (Si3N4) in a microstucture that delivers strength, excellent refractory properties, and resistance to oxidation and thermal shock.
Thermocouple protection tubes made from Halsic-N are reportedly ideal for the melting of non-ferrous metals such as aluminium and magnesium, where its strong metal-repelling characteristics help ensure long service life and optimum performance. With flexural strength of 160 MPa, Halsic-N can be coated with a specially formulated coating for the firing of porcelain or technical ceramics.
“Kiln furniture is subject to intense demands on its performance, including rapid heating and cooling, making materials choice and design absolutely critical,” said Michael Rozumek, Ph.D., R&D director. “Following extensive testing and analysis, our team of engineers has arrived at a formulation that we believe delivers all of the key performance attributes demanded by kiln users. With an extensive standard range and the ability to form shapes to meet customers’ own design needs, we believe Halsic-N is set to become the material of choice for kilns across a broad spectrum of applications.”
Standard designs available include setter plates, beams and supports in a range of sizes, while components can also be manufactured to meet customers’ requirements.
