Background McDanel Advanced Ceramic Technologies LLC is a leading manufacturer of high quality refractory tubes and sheaths, supplying major heat-using industries worldwide for over 80 years.
They offer high purity alumina, mullite and partially stabilized zirconia tubing. The impervious fine grained ceramic products are used in many applications where it is necessary to provide a protective atmosphere at high temperatures without contamination. Material selection depends upon operating working conditions such as peak temperature, chemical environment and abruptness of temperature change.
Various rods, tubes, crucibles, dishes, boats, trays and discs are standard items and a significant capability for producing custom shapes is available. AluminasAluminas (Al2O3) are generally more chemically resistant, harder, stronger and more refractory than mullite.
