ZIRCAR Refractory Composites, Inc. produces a comprehensive line of advanced high performance ceramic-ceramic composite materials and related products. Our materials are used around the world in the most demanding thermal, structural and electrical insulating applications ranging in temperatures from 600C(1112F) to 1650C(3002F). For over twenty-five years, we have been a problem-solver working with our customers to resolve their thermal management problems. We have developed products that have become industry standards for induction melting, forging and heat treating applications, investment casting, glass processing, hot pressing, as well as many high temperature electrical applications.

Application Sheet


Application: Separator for Sintering Operations

Product: Refractory Sheet Type RS-DR

Application Information: In this application, Refractory Sheet Type RS-DR acts as a separator in the sintering operation to manufacture steel filters. The "green form" filter which is made from steel powder processed into tape preforms plus binders, is heated to 1204C(2200F) in a hydrogen atmosphere. To mass produce these filters, trays of green forms with separating layers of RS-DR are passed through the furnace for heating.

Benefits: The benefits of using RS-DR in this application are:

RS-DR withstands the operating temperature well; RS-DR has the desired strength properties;

RS-DR has superior thermal shock capabilities and in various independent tests, conclusively out performs available hard ceramics;

RS-DR allows repeat cycles- it is reusable in this application to approximately 15 cycles which translates to cost savings.
