Additionally, the development of hBN nanoparticles has opened new opportunities in fields, such as the biomedical, dental, skincare, and plastic industries, further favoring the market growth.

Global Hexagonal Boron Nitride Market Restraints

• High production cost: The complex manufacturing process of hexagonal boron nitride involving high temperature and specialized equipment leads to significant capital investment and results in elevated product costs. This can make it difficult for end-users to adopt hBN on a large scale and restrict penetration across cost-sensitive applications. The high pricepoint of hBN remains a key factor hindering adoption.
• Presence of alternatives: Hexagonal boron nitride faces competition from other advanced ceramic materials such as silicon nitride, aluminum nitride, and synthetic graphite, which possess similar properties. This can limit hBN utilization for certain applications wherein substitutes are readily available at more affordable costs. The existence of alternatives slows the market growth to some extent.
• Stringent regulatory policies: The global hexagonal boron nitride market is constrained by strict regulations regarding the mining of boron ore which is the key raw material. Borates classified as hazardous under REACH legislation in Europe can limit raw material supply and production capacities. Additionally, stringent norms related to the use of nanoparticles may challenge growth in the personal care and biomedical sectors. Adhering to regulatory compliances results in higher overheads.
