Boron nitride break ring description.
Here a non oxygen stabilization of pan fibers was demonstrated using boron trichloride bcl 3 as the crosslinking agent and ring patterned boron nitride bn surface wrinkles were further demonstrated when the pan fibers are stabilized under the consecutive gases of bcl 3 and ammonia nh 3 due to the thermal shrinking induced mismatched.
Boron nitride chemical formula bn synthetically produced crystalline compound of boron and nitrogen an industrial ceramic material of limited but important application principally in electrical insulators and cutting tools.
Boron nitride or bn is a chemical compound with equal numbers of boron and nitrogen atoms the hexagonal form hbn corresponding to graphite is the softest and most stable form among bn polymorphs and is therefore used as lubricant and an additive to cosmetic products.

In this study we have used two kinds of boron nitride rings from a twisted bn sheet in the same chirality created by different mechanisms.
The hexagonal form corresponding to graphite is the most stable and soft among bn polymorphs and is therefore used as a lubricant and an additive to cosmetic products.
