CRYSTAL SiC | Washington Mills

CRYSTAL SiC is an ultra-high purity silicon carbide grain or powder, specially manufactured to achieve extremely low levels of impurities. GDMS is used to measure the impurities within Crystal SiC because unlike green or black silicon carbide, the impurity levels are so low that traditional measurement techniques will not detect their presence.
