Liquid-Phase Sintered Silicon Carbide with …

SiC was sintered with AlN and Y2O3 as sintering additives by spark plasma sintering (SPS). Using nano-sized β-SiC powder as the starting material, the sintered density reached about 95% of theoretical at 1800-2000oC for 10min. The β to α phase transformation of SiC was not found by XRD. The secondary phase such as Y2O3 decreased as the firing temperature was elevated, and β-SiC monophase

Reference Materials - Sympatec

Reference material is used for re-certifiion of a Sympatec instrument. Sympatec prefers to test the precision of the instruments by real powder instead of reticles (transparencies with images of particles), because the proper function of the dispersing system, which is essential to a precise measured result, can only be tested by real powder.
