New Lightweight Cordierite Material is Introduced
Dyson Ceramic Systems (Stoke-on-Trent, Staffs, England) has introduced Dylite, described as a revolutionary new cordierite material that is almost half the weight of standard cordierite. This gives kiln furniture users the potential to obtain refractory weight savings of up to 50%, to achieve faster firing cycles and to reduce energy consumption substantially.Developed by the company over a period of three years, Dylite is said to offer additional benefits to refractory system users. Thermal shock resistance is improved over standard cordierite, giving longer refractory life, while its lower specific heat capacity enables quicker heating and cooling to take place.
As a consequence, rapid firing is therefore a real possibility with Dylite, offering the opportunity to increase kiln speed and throughput. Refractory coating is also improved. Dylite's high porosity enables cover wash to be more easily absorbed and adhere to the refractory, giving an improved protective coating. Refractory life is therefore prolonged, with fewer reapplications required.
Dylite has a variety of applications within the tableware sector, including bone china biscuit profile setters and cup rings, total foot support setters and earthenware bedding rings. It is also said to be ideal for kiln car bases, as baffle and cover batts. When used as perimeter blocks in conjunction with prill infill, a new lightweight refractory material ideal as a loose fill insulator, further energy savings are possible.
