| GE Advanced Ceramics boron nitride (BN) powder grades AC6028, AC6103, and AC6091 are large agglomerates of well-defined individual (~10 µm) crystals. These low- to medium-density grades are processed to achieve tailored surface areas; they are pourable and exhibit good lubrication and thermal conductivity properties in finished products. AC6091 is similar in particle size to AC6028 (average particle size of 125 µm), but is refined to achieve a lower surface area and higher tap density. Applications: These grades are ideal for use in thermal spray applications as well as metal-matrix and ceramic composites for wear applications such as high-performance brake linings. They are also used in heating elements and adhesives, pastes, and potting compounds with increased thermal conductivity and high electrical resistivity.
