Previous studies have shown that workers in the silicon carbide (SiC) industry have an overall increased risk of lung cancer. In a Canadian study, the standardised mortality ratio of lung cancer was 1.7 (95% CI 1.1 to 2.5). 1 Cancer incidence among Norwegian SiC workers is previously studied in two follow-ups, with end points 1996 and 2005, with standardised incidence ratios (SIR) of lung

INTRODUCTION Silicon carbide (SiC) is produced by mixing quartz sand and petrol coke in an electric resistance furnace (Smoak et al., 1978).Small-scale production of SiC was started by Edward Goodrich Acheson in the 1891 and has risen steadily since then (Smoak et al., 1978).).
powder was successfully synthesized in RF-plasma systems from different types of precursors, such as silicon and CH4 [13,14], trichloromethyl silane , silicon monoxide and methane , chlorosilane and methane , organosilanes , and coarse SiC
