Power Generation Products
In 2020, natural gas-powered turbines provided about 25% of the world’s electricity, reducing the demand for coal. Morgan’s ceramic cores are essential to the manufacture of the blades within these turbines that maximise the turbine’s power efficiencies.
In 2020, about 4% of the world’s electricity was generated by photo-voltaic (PV) solar panels. Morgan’s fused silica rollers transport flat glass through tempering kilns to produce damage-resistant glass covered Gen I mono-crystalline and polycrystalline and Gen II thin film solar panels. Plasma treating of flexible films for Gen III solar cells are enabled by Morgan’s alumina plasma corona tubes.
Power electronics, which are used within electric vehicle charging stations and inverters that convert solar generated direct current into alternating current, are made using wafers made from Morgan CVD silicon carbide high-purity source material. Also, the gallium nitride or silicon carbide epitaxy layer on the surface of the wafers are deposited by MoCVD equipment that utilise Morgan CVD silicon carbide precision machined components.
The hardware is used within:
- Glass tempering kilns
- Vapour distribution and deposition systems
- Film corona treatment systems
- Investment casting process
- Gen I, II, and III photovoltaic solar panels
- Power electronics for inverters and EV charging stations
- Industrial gas turbine engines

Power Generation Ceramics Questions
Why is high purity SiC required for SiC wafers?
High purity silicon carbide source material is typically defined as silicon carbide with a purity level of 6N (99.9999%) or greater. The purity of this source material (among other factors including its form) can influence the resulting silicon carbide crystal (or ingot) uniformity and quality from which the SiC wafers are produced. Such wafer uniformity defects can negatively affect the performance of the subsequent semiconductor power device.
Why are CVD SiC carriers used to hold wafers during the deposition of the epitaxy layer?
Solid CVD silicon carbide (SiC) wafer holders or wafer carriers are often preferred over holders made of graphite that are coated with SiC, for a variety of reasons:
- A monolithic material design can provide greater temperature uniformity resulting in a more consistent epitaxy layer deposited upon the wafer being held.
- The surface morphology of a machined, solid CVD SiC holder can be easier to control versus a coated surface morphology
- Besides being inert to the hot process gasses of the epitaxy reaction, the holder must also be able to resist the cleaning process (such as wet etching) employed to remove materials that deposit themselves onto the holder surface during the epitaxial reaction. A solid SiC carrier is considered more durable versus a SiC coated holder in both these circumstances.
What is a physical vapour transport tube?
Physical vapour transport (PVT) is a process where a source material is heated to its sublimation point, transforming the material into a gas or vapour. The PVT tube directs the flow of the resultant hot vapour to a surface upon which the vapour will be deposited, typically to form a film. Because such hot gasses can be corrosive, the tubes must be constructed of a material that is chemically inert to the hot gasses so the tube itself does not become a source of impurities in the resulting deposited film.
