Performance Characteristics:
SiC is black quartz sand and petroleum coke (smokeless acetylene) as the main raw material, smelted by above 2500C in large size electric furnace. So it has high density, big crystal and high purity, black opaque body hexagonal crystal, MO-hardness in the 9.15-9.5. After diamond and boron carbide, crisp and sharp performance, and certain degree of conductive heat, the hardness and toughness are superior to green silicon carbide when same sic content.
Relative Fields:
Lo resistance SiC processing using low-intensity black metal and non-metallic, cancer or materials and the electronic industry.
