MORGAN ADVANCED MATERIALS Expands Silicon Carbide Production

MORGAN is able to produce both sintered silicon carbide (PS5000 – SiC) and graphite loaded (PGS3 – SiC) silicon carbide materials primarily for mechanical seals and radial bearings. These products are used in domestic water pumps, heavy duty industrial water, and chemical pump applications, including cooling pumps for plastic injection moulding machines.

Global demand for silicon carbide in pump designs is soaring, largely as a result of the technical and cost benefits this ceramic grade can provide over other materials such as tungsten carbide and alumina.  MORGAN’s silicon carbide ceramics continue to give high performance when pumping contaminated, abrasive and corrosive fluids and provide excellent sealing at high pressures. They have a low thermal expansion coefficient and high thermal conductivity which contributes to its outstanding thermal shock resistance; this is particularly important if pumps have a risk of running dry. Overall pump reliability is increased and as a result companies experience less downtime, resulting in reduced operational costs. The move to increase the silicon carbide manufacturing capability is a natural progression for MORGAN, which has been manufacturing alumina ceramics for pump applications for the last 50 years. The company has recently completed investment in new kiln and manufacturing equipment, capable of firing and processing high volume silicon carbide products through a dedicated cell. This has enabled MORGAN to form near press-to-size silicon carbide components up to 80 mm in diameter, with detailed design features and precision dimensional tolerances. Chris Paine, Business Development Manager at MORGAN ADVANCED MATERIALS, commented: “This extensive investment enables us to offer seamless production of silicon carbide seal and bearing products, from raw materials to finished parts manufacture at one single site. This means that we can provide the requisite quality assurance for all our products while responding to global demand for high volume manufacturing capabilities.”
