NA series is one of the boron nitride products that is currently developing, with particles smaller than 1 um. lt has two morphologies: granular and single platelet. The average particle size of granular grade is about 50 nm, and the size of platelet-like grade is about 400 nm.

HS series The crystal morphology appears to be single platelet with high crystallinity and low graphitization index. The crystals grow preferred in plane direction and this can be clearly observed under SEM, The crystals have a very high aspect ratio. The product has large crystal size, high purity, low specific surface area, increased density, low soluble Borates, hydrophobic and lipophilic nature and no agglomeration. The overall quality is outstanding and matching the advanced quality level of products from all over the world.

HN series Microscopically,the monolithic structure is composed of 5~20 μm fillet with a thickness of 0.1 μm. The hexagonal boron nitride HN is fully crystallized, the specific surface area is small, and the free Boron Oxide is low.

HF series The crystals appears to be smaller, thick, and round shaped. HF has medium crystallinity, small particle size, relatively large specific surface area. high purity, and low water-soluble Boron Oxide content.

HC series has medium to high crystallinity and excellent high temperature and oxidation resistance. Microscopically, HC is a small agglomerate of smaller crystals with an overall medium specific surface area. The free Boron Oxide of HC and HC8 is typically higher than for other grades.
