Material Spotlight | Semi-Insulating Silicon Carbide (SI-SiC)

High Resistivity. High Temperature. High Performance.

Semi-insulating silicon carbide combines the inherent thermal and chemical stability of SiC with high electrical resistivity, making it an important material for demanding semiconductor and high-frequency applications.

Its applications include:

• Semiconductor substrates
• RF / microwave devices
• GaN-on-SiC applications
• Power electronics
• High-frequency electronic devices

But processing SI-SiC is not simply about reaching a high temperature.

For powder-based components, debinding is an important first step before high-temperature sintering. A typical process may involve controlled binder removal at around 1000°C, followed by high-temperature sintering under a controlled atmosphere.

Key processing considerations include:

• Controlled debinding — gradual binder removal to reduce defects and cracking
• High-temperature sintering — stable heating for densification and material performance
• Atmosphere control — maintaining the required vacuum or inert environment
• Temperature uniformity — supporting consistent sintering throughout the work zone
• Controlled cooling — reducing thermal stress after high-temperature treatment

Material Spotlight | Graphite
From Carbon to Graphite — High-Temperature Processing Makes the Difference.
Graphite is one of the most important carbon-based materials for high-temperature applications, valued for its excellent thermal and electrical conductivity, chemical resistance, and stability at extreme temperatures.
Its unique combination of properties makes graphite widely used in:
• Semiconductor and CVD components
• EDM electrodes
• Metallurgical crucibles and molds
• Energy storage materials
• High-temperature furnace components
• Aerospace and other demanding applications
However, producing high-performance graphite often requires more than simply heating carbon materials.
Graphitization is a critical high-temperature process in which carbon materials are transformed into a more ordered graphite structure. Precise temperature control, heating uniformity, atmosphere protection, and process stability are essential for achieving the desired material properties.

Material Spotlight | Tungsten Carbide (WC)
A critical material. A tightening supply chain. A growing need for recycling.
Tungsten Carbide (WC) is widely used in cutting tools, mining and drilling equipment, wear-resistant components, dies, molds, and other demanding industrial applications because of its exceptional hardness and wear resistance.
But today, WC is attracting attention for another reason.
Tungsten has become an increasingly strategic material.
With tighter export controls and growing concerns over the security of tungsten supply chains, the global industry is paying greater attention to tungsten resources, processed products, and recycling from tungsten carbide scrap. China is also increasingly shifting its tungsten industry toward higher-value processing, while recycled tungsten is becoming an increasingly important secondary resource.
From Scrap to Resource
For manufacturers working with used cemented carbide tools, production scrap, and other tungsten-containing materials, recycling can provide an opportunity to recover valuable tungsten resources and reduce dependence on primary raw materials.
At NOTIAN, we have also been exploring thermal processing solutions related to tungsten carbide recycling and recovery.
Recommended Thermal Processing Solution
For high-temperature processing of tungsten carbide and related tungsten-containing materials, NOTIAN recommends Induction Sintering Furnaces.
Compared with conventional heating approaches, induction heating provides:
✔ Very high processing temperatures suitable for demanding tungsten-based materials
✔ Rapid and efficient heating through electromagnetic induction
✔ Controlled thermal processing for sintering and high-temperature treatment
✔ Vacuum / protective atmosphere processing for improved material protection
✔ Customized equipment design according to material composition, process requirements, and production capacity
As tungsten resources become increasingly strategic, recycling and high-value utilization of tungsten-containing materials may become an increasingly important part of the supply chain.
At NOTIAN, we are continuing to explore thermal processing technologies for tungsten carbide and tungsten recycling.
Could tungsten carbide recycling become an important source of tungsten for the future?
