Materials
MTC materials used within pump applications include 96% & 99.5% Alumina, Zirconia & Silicon Carbide.
Alumina offers a combination of good mechanical and electrical properties suitable for a wide range of applications. It has a high compressive strength, hardness and is dense, non-porous, has low toxicity and vacuum tight. It has excellent dimensional stability across very wide temperatures and resists chemical attack.
Silicon Carbide materials exhibit superior mechanical, wear and thermal shock resistance properties which provide excellent seal and bearing performance for heavy duty applications.
Ceramic materials can be produced in a range of purities and/or with additives designed to enhance certain properties depending on the requirements of the application (hence the different grades listed above). It can be formed by different ceramic processing methods and can be machined or net-shaped formed to produce a wide variety of sizes and shapes. In addition ceramic components can be readily joined to metals or other ceramics using metallising and brazing techniques.
