Silicon Carbide - excellent for high temperature applications 
Different grades of silicon carbide offer high thermal/electrical conductivity well beyond other ceramic materials.
Silicon Carbide is industrially produced by sintering, reaction bonding, crystal growth, and chemical vapor deposition (CVD).

Silicon carbide offers low density and high stiffness, as well as extreme hardness and wear resistance. The CVD material can be produced with such low electrical resistance (around one ohm cm) that it can be considered a reasonable conductor of electricity. Although fabrication of precision parts from blanks of CVD SiC must be completed via diamond grinding technologies, this electrical property allows fabrication of fine features by use of EDM methods, which can be useful for generating tiny holes with high aspect ratios.

Another interesting feature of silicon carbides is their relatively high thermal conductivity. Here again, the CVD material excels by achieving at least 150 W/mK, which exceeds that of common steels and cast iron. Thermal conductivity does decrease with temperature and must be considered carefully against specific applications.

CVD silicon carbide has been used for many years in semiconductor processing applications, where excellent thermal shock resistance and resistance to erosion by high-energy plasmas are required. CVD properties can benefit all types of applications, including electrodes and sputter targets; components like susceptors, gas distribution plates, chucks, heaters; and edge rings or any application that requires electrical conductivity, wear resistance, and thermal shock resistance.

Insaco Inc. has many years of experience fabricating precision parts from this material. Our technology consists of diamond grinding of CVD silicon carbide in its extremely hard available state. Normally Insaco will source materials from the most appropriate producer and then fabricate to meet our customer’s most stringent dimensional requirements.

select materials of interest based on what is most important to your application. Once you specify which properties are most important, the "guide" searches our database of materials and presents you with various materials listing the selected properties ranked as you specify and often includes some other materials provided as references.

Watch>>>Ceramic Manufacturing and Machining Process with Insaco, Inc.

Insaco
Insaco has been fabricating precision parts from all technical ceramics since 1947. Approximately a third of our machining involves sapphire, but our capabilities go way beyond that. Insaco engineers welcome inquiries from designers contemplating specifying technical ceramics for their applications, whether prototype or full production. We only ship parts that meet agreed-to requirements, but are often able to respond to challenges and achieve results others cannot.

High Precision Machining of Hard Materials
Since 1947 Insaco® has been a precision machining and polishing fabricator of parts from all technical ceramics, sapphire, glass and quartz. We machine these materials to very precise tolerances (many times measured in millionths of an inch) for dimension, flatness, wedge and roundness or cylindricity. Our customers typically have a critical application that requires extremely tight tolerances in ultra-hard materials. We also have the capability to grind and polish spherical radius parts in a variety of hard materials, both inside and outside diameters, to optical requirements.

features include:

• Extremely high accuracy and tight tolerance machining
• Lights-out manufacturing
• Machine automation including large capacity envelope
• Automated centerless grinding
• High efficiency/low cost volume production
• Low-volume prototype machining
• 5-axis machining capability
• ITAR compliant
• High-volume robotic machining
• Video inspection and a Class 100 Cleanroom
• Extensive Quality Control protocols
• Sapphire tubes and polishing
