N-92D Alumina purity 92％ Black color ceramics

92％ purity Alumina with mixture of Black color pigment as the base.
N-92D’s Alumina purity is 90.5％, and coefficient of thermal expansion is 8.5×10-6/℃(25～800℃)
Since this material doesn’t reflect light, it is commonly used as machine parts, optical parts, measurement tools, semiconductor manufacturing systems parts, and liquid crystal manufacturing system parts.

N-9B Alumina purity 99％ Black color ceramics

99％ purity Alumina with mixture of Black color pigment as the base.
N-9B’s Alumina purity is 94％, and coefficient of thermal expansion is 8.2×10-6/℃(25~800℃)
Since this material doesn’t reflect light, it is commonly used as machine parts, optical parts, measurement tools, semiconductor manufacturing systems parts, and liquid crystal manufacturing system parts.
