Recrystallized Silicon Carbide

Recrystallized silicon carbide (RSiC) is an exceptional material with unparalleled mechanical and thermal properties, boasting outstanding mechanical and thermal characteristics as well as possessing an enhanced microstructure which enhances these attributes even further.

RSIC boasts high thermal conductivity, excellent corrosion resistance, and can be formed into complex shapes without cracking or chipping. Furthermore, its properties enable it to withstand slag attack and flame erosion for added resilience.

Superior Mechanical Properties

Recrystallized silicon carbide offers excellent dimensional stability at high temperatures and extreme durability in harsh operating environments, unlike cordite and mullite support materials that degrade under pressure, such as cordite or mullite. Because of this strength and resilience, recrystallinelized silicon carbide makes an excellent material choice for applications such as kiln furniture that require it to withstand constant use under extreme conditions.

Silicon carbide ceramics come in various polymorphs, with alpha SiC (a-SiC) having the most popular one being Wurtzite crystal structure similar to diamond. Zin blende SiC, also known as beta SiC is much less prevalent; yet has gained increasing interest as an application support due to its higher surface area and superior mechanical properties compared with alpha SiC polymorph.

a-SiC polymorph is frequently employed in alumina-refractory ceramics and high temperature applications as an electrode material due to its extremely high thermal conductivity, excellent oxidation resistance and good abrasion resistance. Furthermore, b-SiC is often employed as an electrode material in ceramic furnaces, ceramic insulators and glass manufacturing processes.

Self-bonded, nitride-bonded silicon carbide refractories are created through an innovative process. Beginning with silicon carbide powder, these refractories are formed into complex shapes using special tools before being sintered at temperatures reaching 2500deg C for sintered use. Their thermal conductivity is 10 times that of fireclay refractories while offering superior corrosion and oxidation resistance, offering high hot strength with very little water absorption – perfect for applications such as slag attack and flame erosion applications.

High Corrosion Resistance

Recrystallized silicon carbide not only offers superior mechanical properties, but is also extremely resistant to corrosion – an invaluable quality in any material that comes into contact with harsh environments like high-temperature kilns and metal smelting. Furthermore, recrystallized silicon carbide makes a good material choice for components exposed to chemicals which may corrode over time.

To increase RSiC’s corrosion resistance, various acids can be applied. Hydrofluoric acid in particular penetrates deeply into open pores of RSiC and etches their inner wall surfaces while simultaneously decreasing low-resistance carbon layering on their interior surfaces.

Increase the corrosion resistance of RSiC by applying a nitriding treatment, which changes its metallic silicon to silicon nitride and bonds the grains together. Nitriding treatments may be done either after or before sintering has taken place.

Since nitride bonded RSiC does not shrink during sintering, it is less likely to experience internal stress and crack or bend upon being formed into shape. As such, this material can be utilized in more diverse applications than other porous silicon carbide materials, including car parts that withstand wear-and-tear, aerospace components, military applications and many others.

High Thermal Conductivity

Silicon carbide (SiC) is an inorganic chemical compound composed of silicon and carbon. While naturally found as the rare mineral moissanite, mass production began in 1893 using powder and crystal form for use as an abrasive. Sintering also bonds SiC together into ceramic materials with superior strength and endurance that may be found in bulletproof vests.

Recrystallized silicon carbide (RSiC) is a variation of SiC that boasts superior overall properties due to its unique microstructure. Composed of interlocking plate-like grains that run parallel with its surface, RSiC offers superior strength, toughness, wear resistance, high dimensional stability and low thermal expansion – perfect for high temperature applications.

RSiC can be made through various processes, such as slip casting, extrusion and injection molding. After being formed into its final shape it is sintered at high temperatures causing recrystallization to take place and create its characteristic microstructure – this also removes binder material, leaving pure RSiC behind.

Recrystallized silicon carbide (RSiC) can be produced on an industrial scale for many different applications, from manufacturing kiln furniture and wear components with its excellent corrosion and oxidation resistance to fuel cell components and diesel particulate filters thanks to its high thermal conductivity and low shrinkage properties. Recrystallized SiC is ideal for large scale production due to its vast production capacities and diverse uses; such as wear resistance. Recrystallized SiC is often preferred over reaction-bonded RSiC for applications involving corrosion or high temperature environments such as making wear components for manufacturing kiln furniture due to its corrosion-resistance; such as wear components used for making wear components in industrial settings due to its resistance properties against corrosion, oxidation and high temperature applications as well as fuel cell components and diesel particulate filters due to its thermal conductivity properties and low shrinkage potential compared with reaction-bonded RSiC which requires special care during production.

Wide Range of Applications

RSiC can be utilized in various applications due to its superior mechanical, thermal and electrical properties. With superior corrosion resistance and higher strength than other porous ceramic materials, it can withstand high stresses and temperatures while its low coefficient of expansion ensures it keeps its shape without warping or warping under heat stress.

Slip casting, extrusion and injection molding can all be used to fabricate RSiC into complex shapes, making it more user-friendly across a wide variety of applications. Thanks to its excellent high temperature strength and oxidation resistance properties, RSiC is often chosen for making kiln furniture due to its exceptional high temperature strength and wear resistance; additionally it has excellent wear resistance so can be used in manufacturing of abrasives, grinding tools, cutting tools and other industrial equipment.

Additionally, RSiC can be used to produce protective armor plates for military equipment and vehicles. Due to its excellent mechanical properties, this innovative material can help improve performance and lifespan while its corrosion-resistance reduces risks during deployment and transport; making RSiC an excellent option for many uses in both the military and aerospace industries.
