Thermic Edge Coatings: Ten Years of Independent Ceramic Coatings Expertise

Published: 4th February 2026

Founded in 2016, Thermic Edge Coatings celebrates ten years as a specialist and independent provider of high purity ceramic coatings for high temperature and vacuum applications.

Thermic Edge Coatings operates as part of the Thermic Edge Group, which includes Thermic Edge, Thermic Edge Ceramics and Graphite, and Thermic Edge Europe. Within the group, Thermic Edge Coatings is dedicated exclusively to the development, application, and analysis of advanced ceramic coatings, supporting industries where surface stability, cleanliness, and process reliability are critical.

A Decade of Independent Coatings Expertise

Since its founding, Thermic Edge Coatings has remained an independent coatings provider, retaining full control over coating processes, material selection, and quality standards.

This independence enables close collaboration with customers who require ceramic coatings for new system builds, component refurbishment, lifetime extension, or performance improvement in existing equipment. Over the past decade, this approach has supported long term partnerships across semiconductor manufacturing, research laboratories, and advanced industrial processing.

The business is led by General Manager Sharon Crooks, with technical delivery supported by experienced CVD engineers and senior process technicians, ensuring consistent process control and repeatable coating performance.

Silicon Carbide Ceramic Coatings for Extreme Environments

Thermic Edge Coatings specialises in silicon carbide ceramic coatings designed to protect components operating in aggressive conditions where uncoated materials would degrade rapidly.

These coatings are commonly applied to components such as susceptors, wafer carriers, heater assemblies, fixtures, liners, and process hardware manufactured from graphite, ceramics, and refractory metals exposed to:

• High temperatures
• Vacuum and controlled atmospheres
• Corrosive and reactive process gases
• Particle sensitive semiconductor manufacturing environments

Silicon carbide ceramic coatings provide strong resistance to oxidation and corrosion while maintaining surface stability during repeated thermal cycling. This makes them particularly suitable for ceramic coatings for semiconductor manufacturing, silicon carbide coatings for vacuum systems, chemical vapour deposition equipment, thin film applications, and high temperature vacuum furnaces.

Innovation in Cubic Silicon Carbide Coatings

As part of its ongoing development work, Thermic Edge Coatings has advanced its silicon carbide offering through SiC3, a proprietary cubic silicon carbide ceramic coating.

SiC3 was developed in response to increasing demands within semiconductor, CVD, and vacuum based processes, where surface purity, particle control, and long-term stability are essential. Rather than relying on generic coating formulations, Thermic Edge Coatings refined deposition parameters and coating structure to improve real world performance.

The cubic silicon carbide structure of SiC3 contributes to reduced particle generation, improved resistance to oxidation and corrosion, and stable surface behaviour under repeated thermal cycling. These characteristics make it particularly suitable for contamination sensitive processes and long duration high temperature operation.

Controlled CVD Coating Processes

All ceramic coatings applied by Thermic Edge Coatings are produced using carefully controlled chemical vapour deposition processes.

CVD enables coatings to be deposited with:

• Uniform thickness across complex geometries
• Effective coverage of internal features and blind holes
• Strong adhesion to base materials
• Dense, high purity ceramic layers

For porous substrates such as graphite, the coating process penetrates below the surface, improving durability and reducing the risk of subsurface degradation during high temperature operation.

In House Engineering and SEM Analysis

A key strength of Thermic Edge Coatings is it’s in house technical capability.

Coating processes are overseen by experienced CVD engineers and senior process technicians who manage deposition parameters, inspection, and refinement. This allows coatings to be tailored to specific materials, geometries, and operating environments.

To support quality assurance and development, Thermic Edge Coatings performs scanning electron microscope analysis. SEM analysis is used to examine coating structure, thickness uniformity, and surface condition, supporting both routine inspection and continuous improvement of ceramic coating performance.

Applications Across Semiconductor and Vacuum Industries

Thermic Edge Coatings supports a wide range of high technology applications, including:

• Semiconductor wafer processing equipment
• Chemical vapour deposition reactors
• Thin film and epitaxial growth systems
• High temperature vacuum furnaces
• Research and development facilities

In these environments, silicon carbide ceramic coatings help maintain clean surfaces, reduce contamination risk, stabilise process conditions, and extend component service life in aggressive operating conditions.

Part of the Thermic Edge Group

As part of the wider Thermic Edge Group, Thermic Edge Coatings works alongside teams specialising in ceramics, graphite components, and vacuum technology, while maintaining a clear and independent focus on ceramic coatings.

This structure allows customers to access dedicated coatings expertise supported by a broader materials and engineering ecosystem.

Looking Ahead

After ten years of independent operation, Thermic Edge Coatings continues to refine ceramic coating technology through process optimisation, materials analysis, and close collaboration with customers.
