Below highlights some of the benefits of using XeraBond KF compared to more traditional methods.
XeraBond KF has been developed as a superior kiln furniture product.
XeraBond KF is a stronger and more chemically stable conventional refractory product with a protective coating for high and low temperature oxidation resistance. It also has the advantage that it does not require turning because it does not warp in service.
Lightweight kiln furniture can help pottery producers save energy, improve productivity—and increase profits.
XeraBond KF is 10 to 28 times stronger than traditional silicon carbide and cordierite refractory materials, which allows for substantially lighter kiln furniture components, such as batts (kiln shelves), support beams and support posts.
XeraBond KF kiln batts are thinner (5⁄16” or 8 mm.) than the typical 5⁄8” (16 mm) to 1” (25 mm) traditional silicon carbide or cordierite batt. Thinner cross-sections and excellent thermal properties result in faster heat transfer and greater energy efficiency—as a result, faster firing cycles can be adopted, using less energy and, depending on the percentage of the total kiln load devoted to kiln furniture, thinner kiln shelves can significantly reduce the total amount of refractories while increasing ware capacity.
The light weight of XeraBond KF batt is one of its most important factors, because less heavy lifting is required when stacking and unstacking kiln loads.
Pottery producers have also discovered that XeraBond KF batts require less maintenance compared to conventional kiln furniture. While for some applications a washcoating may be required, the low porosity of XeraBond KF does significantly reduce or eliminate other labor-intensive maintenance operations.
Although XeraBond KF kiln furniture is primarily used in gas-fired kilns, it can also be successfully used in some soda-, wood- and electric-fired applications because of its ability to resist glaze fusing onto the batt surface.
In addition, Xerabond KF can be used for lower temperature applications (800-1100°C) because the protective layer increases the oxidation resistance, which prohibits the use of conventional silicon carbide refractories. This protective layer is self-healing, if damaged during handling.
Traditionally, the manufacturers of pottery, sanitaryware and building products have used cordierite, alumina or silicon carbide based refractories for kiln furniture. These refractory kiln furniture products are heavy and have inherent problems. With the exception of SiSiC, these products are porous and require a washcoating of alumina or zircon to prevent glaze sticking to the batt.
We are continuing our research and development into other Industrial and technical environments, and are constantly seeking to meet new challenges.
XeraCarb materials are currently being evaluated for use as personal body armour with the research sponsored by the UK’s Ministry of Defence.
This material offers significant advantages over existing armour in terms of the cost, shape and size of components which are possible and in terms of the total system weight.
