Thermic Edge Ltd is the sole manufacturer of high purity Cubic Silicon Carbide (SiC3) and Cubic Titanium Carbide (TiC3) ceramic coatings, that can be applied to purified graphite, ceramics and refractory metal components.
Thermic Edge Ltd is the sole manufacturer of high purity Cubic Silicon Carbide (SiC3) and Cubic Titanium Carbide (TiC3) ceramic coatings, that can be applied to purified graphite, ceramics and refractory metal components.
These very high purity coatings are mainly intended for use in the semiconductor and electronics industries, for protecting wafer carriers, susceptors and heating elements from corrosive and reactive environments such as MOCVD and EPI processes, used for wafer processing and device manufacture. The coatings are also suitable for vacuum furnaces and sample heating in high vacuum, reactive and Oxygen environments.
Thermic Edge’s state of the art machine shop allows us to offer a complete solution including manufacture of the base graphite, ceramic or refractory metal component, and the SiC3 or TiC3 ceramic coating. We also offer a coating only service for customer supplied parts.
SiC3 is our trade name for our high purity cubic Silicon Carbide ceramic coating. It is applied to components to protect them from Oxidation or reaction with other gasses at high temperature. The SiC3 coating is applied using a high temperature, very high purity Chemical Vapour Deposition (CVD) reactor.
SiC3 coating is an electrical insulator, incredibly hard and has good corrosion and oxidation resistance. It can withstand temperatures up to 1600C at atmospheric pressure.
SiC3 Cubic Silicon Carbide ceramic coating can be applied to the following materials:-
SiC3 Cubic Silicon Carbide ceramic coating can be used at high temperature in the following environments:-
TiC3 is our trade name for our high purity cubic Titanium Carbide ceramic coating. It is applied to graphite components to protect them from vaporisation in high vacuum (HV) and Ultra High Vacuum (UHV) at high temperature and reaction with other gasses at high temperature. The TiC3 coating is applied using a high temperature, very high purity Chemical Vapour Deposition (CVD) reactor.
TiC3 coating is a very good electrical conductor and can withstand very high temperatures up to 3000C. It has a very low vapour pressure, enabling it to operate at high temperature in high vacuum and Ultra High Vacuum (UHV). It is incredibly hard and has good corrosion resistance. It does not like oxygen however and will readily react with O2.
TiC3 Cubic Titanium Carbide ceramic coating can only be applied to high expansion graphite products, as it has a CTE of about 7x10e-6 mm/C
TiC3 Cubic Titanium Carbide ceramic coating can be used at high temperature and also very high vacuum in the following environments:-
SiC3 Cubic Silicon Carbide coating has the following advantages over conventional SiC coatings:
TiC3 Cubic Silicon Carbide coating has the following advantages:-
Thermic Edge Limited are committed to lead the industry in delivering innovative, high-quality high-temperature applications, backed by unparalleled customer service.
To be a beacon of innovation and excellence, inspiring positive change and leaving a lasting impact on our industry and the environment
