Silicon Carbide Products
IPS Ceramics offers all the principal types of silicon carbide products; a long lasting, rugged, dependable performer in many challenging environments. Our products including Beams, Batts, plates, rollers are made to tight dimensional tolerances and have an excellent load-bearing ability at higher temperatures. Silicon carbide retains most of its mechanical strength at elevated temperatures and exhibits very low levels of creep, making it the first choice for load-bearing applications in the range 1300ºC to 1650ºC (2400ºC to 3000ºF).
Silicon carbide components provide outstanding thermal shock resistance but unlike traditional ceramics, they also combine low density with high mechanical strength. Additionally, these products offer extreme hardness/abrasion resistance and outstanding chemical stability in aggressive environments.
Where temperatures are high (1300ºC to 1650ºC) or heavy product loading, SiC batts are often the best choice. If replacing cordierite or mullite batts on the kiln, then much thinner SiC batts can be used (6-10mm thickness) due to the improved creep resistance and strength. A batt thickness of 6-10mm is often enough. Batts can be manufactured in either nitride-bonded SiC (below 1400°C) 2552ºF or recrystallised SiC materials (up to 1600°C) 2912ºF.
SiSiC beams are used extensively as supports in kiln and furnace construction, and as part of kiln furniture structures. The material has superb strength and creep resistance, allowing beams to be spanned across larger widths & lengths of kiln cars (kiln structures). Cross-sections from 20 x 20mm to 100 x 100mm are possible, allowing beams to be matched to individual conditions. SiSiC beams are generally unaffected by common kiln atmospheres and typically provide several years of service.
The use of silicon carbide for industrial burners is now well proven technology, offering improved temperature uniformity and increased control.
In any industrial heating process perhaps the most critical aim is to provide a carefully controlled temperature profile within the kiln or furnace. Whether the fuel is natural gas, LPG or oil, the location of the burners is a potential hot-spot within the kiln.
One-piece adjustable props can be manufactured to suit individual production requirements; prop lengths up to 2000mm are possible and teeth spacing can be tailored to your requirements. The result is a system that provides maximum flexibility in shelf / batt placement within the kiln. Props are manufactured in ReSiC allowing use in high temperature firings (up to 1600°C) 2912ºF.
Tubes and Rollers
Tubes can be manufactured up to 3000mm in length, with diameters and wall-thickness tailored to your specific loads.
IPS Ceramics slip-cast saggars can be used for numerous applications, including calcination and refining processes. Our SiSiC material has no open porosity, thus reducing the risk of absorption. The saggars have a very hard, smooth surface, that does not shed grains or dust; a key advantage when sintering/melting high value materials.
IPS Ceramics is happy to work with customers to design bespoke shapes. Slip-casting allows complex shapes and thin walls to be produced to suit your specific needs. Recent examples include burner-flame deflectors and adjustable post feet.
This process is very cost-effective, making small order quantities practical.
These nitride-bonded SiC setters are often used for porcelain manufacture where firings are above 1250oC (2280oF). The NSiC material offers excellent resistance to hot-bending and is very strong; setters can be made thinner and lighter (6mm thick is typical).
The setters are used with separate ‘legs’ so that they can be stacked several layers high (to suit kiln space). Legs can be manufactured to requested lengths and supplied in SiC, alumina or mullite depending on conditions.
Heating elements are widely used in various high-temperature electric furnaces, as well as in other electric heating devices. The range of IPS heating elements are manufactured from recrystallised high-purity alpha silicon carbide (SiC), which is a superb performer in high-temperature applications, and it is characterised by anti-oxidisation, anti-corrosion, long service life, minimal deformation, with easy installation and maintenance.
