Hexagonal Boron Nitride (h-BN): High-Purity "White Graphene" Powder, Now Manufactured in Indonesia

Thermal management in electronics runs into a stubborn contradiction: a filler that conducts heat well enough to pull it away from a hot component usually conducts electricity too which is the last thing you want touching a circuit board or a battery cell. Metals and most carbon fillers force that trade-off. Hexagonal Boron Nitride (h-BN) is one of the few materials that doesn't: it moves heat efficiently while remaining electrically insulating, which is exactly why it's earned the nickname "white graphene."

A h-BN powder with reliably low impurity content and controlled particle size has traditionally meant importing a specialty ceramic material into Indonesia and h-BN is also moisture-sensitive, which makes long transit and storage conditions a real risk to its usable quality. That's changing.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, is Indonesia's first private nanomaterials research startup manufacturing research-grade h-BN locally. Here's what h-BN actually is, why its purity and particle size matter, and where it's being used in current research and industry.

What Is Hexagonal Boron Nitride (h-BN)?

Hexagonal boron nitride shares the same layered, honeycomb-lattice structure as graphite alternating boron and nitrogen atoms in place of graphite's all-carbon rings which is why it's often described as graphene's electrically insulating cousin. That structural similarity gives h-BN excellent thermal and chemical stability, high electrical insulation, and good in-plane thermal conductivity, along with a naturally lubricious, platy morphology similar to graphite's.

What actually determines how well a given batch performs is its purity and particle size. Residual free boron oxide and metallic impurities like Fe, Ca, Mg, and Al don't just sit inertly in the powder they interfere with dispersion in a polymer matrix and can degrade the electrical insulation properties that make h-BN valuable in the first place. Particle size, in turn, controls how the powder packs and disperses: too coarse and it won't form a continuous thermal pathway through a thin composite layer; too fine and it becomes difficult to disperse without agglomerating.

ITNANO's h-BN is supplied at ≥99% boron nitride purity, with free boron oxide capped at ≤0.3% and metallic impurities (Fe, Ca, Mg, Al) each held below 0.006%, at an average particle size of 1 µm giving a consistent, low-impurity powder for applications where dispersion quality and insulation performance both matter.

Where h-BN Is Being Used

Thermal management in polymers and electronics

h-BN is one of the most widely used thermal fillers for polymer composites precisely because it lets a formulation conduct heat away from a hot component without turning the composite into an electrical conductor. That combination makes it a common choice for thermal interface materials, encapsulants, and heat-dissipating housings in electronics that sit directly against live circuitry.

Ultra-thin dielectric layers

In 2D-material research, h-BN is frequently used as an atomically thin dielectric an insulating layer placed between or beneath other 2D materials such as graphene, to isolate them electrically without introducing the surface defects and charge traps that bulk oxide dielectrics tend to add.

Protective coatings against corrosion and oxidation

h-BN's chemical inertness and thermal stability make it useful as a protective coating additive, forming a barrier layer that resists oxidation and corrosive attack on the underlying substrate even under elevated-temperature conditions.

Dry lubricants

The same platy, graphite-like structure that gives h-BN its layered insulation properties also lets its sheets shear past one another easily, making it a useful solid lubricant additive for high-temperature or electrically sensitive environments where conventional oil-based lubricants aren't practical.

Why Source h-BN Locally

h-BN is moisture-sensitive, and its packaging notes exist for a reason: the powder needs to be stored in dry, humidity-controlled conditions to keep its surface chemistry and dispersion behavior consistent. A batch shipped internationally spends weeks in transit and customs before it ever reaches a controlled storage environment exposure it can't recover from once particle surfaces have picked up moisture. ITNANO, established by the Titian Research Group's NRE Lab, manufactures h-BN domestically alongside its other 2D-material lines, giving Indonesian labs and manufacturers a powder with verified purity and particle size on arrival, not just on a data sheet from overseas.

Whether you're formulating thermally conductive polymer composites, building 2D-material heterostructures, developing protective coatings, or working with dry lubricant systems, h-BN gives you a rare combination thermal conductivity without electrical conductivity without the import wait.
