The silicon carbide refractories have high resistance to heat, spalling and corrosion as well as high thermal conductivity and strength. They are widely used in matallurgy, ceramics, and electronic parts industries. As a bond for DIALITE refractory joints, the following two types of mortor are available. M-1 For SDC (for special bonding) M-2 For DC-1, DC-2, DC-3, DC-4 (for bonding silicate)
