Specifications for graphite, ceramic and metal are provided on a case-by-case basis, depending upon the end-use application for the fixture. SST utilizes the highest quality materials available. Isotropic graphite grades are chosen based upon the application. Grain sizes range from 1 micron up to 15 microns. Flexural strengths range up to 16,000 psi (110 N/mm²). Coefficients of thermal expansion (CTE) range from 4 to 8 microns/m°C. Post machining purification and coating services are available. SST has over 50 years of experience with the selection and fabrication of graphite materials for a wide variety of thermal processing uses. SST also has broad experience with design, fabrication and use of metals and ceramic materials for semiconductor and microelectronic fabrication uses.
