長方形の多孔質窒化ホウ素セラミックブロック is a porous ceramic material prepared by advanced technology using high-purity boron nitride (BN) as the substrate. It perfectly combines the inherent excellent thermal conductivity, high temperature stability, excellent electrical insulation and chemical inertness of boron nitride, as well as the unique advantages brought by controllable pore structure. This product is designed to address the challenges of thermal management, medium penetration, and high-temperature insulation in extreme environments, and is an ideal material for high-end fields such as aerospace, electronic packaging, chemical metallurgy, etc.
Product core advantage: Why is rectangular porous boron nitride an excellent choice?
Rectangular porous boron nitride ceramic blocks are not ordinary porous materials, their value lies in their comprehensive and irreplaceable material properties:
- Excellent thermal conductivity and electrical insulation balance: Boron nitride is one of the few materials that can simultaneously have high thermal conductivity (comparable to stainless steel) and excellent electrical insulation (volume resistivity>10 ^ 14 Ω· cm), effectively dissipating heat while ensuring absolute circuit safety.
- 優れた高温安定性 It can work stably in an inert or reducing atmosphere up to 2000 ° C or above, without softening or melting, with an extremely low coefficient of thermal expansion and excellent thermal shock resistance.
- Controllable pore structure and high specific surface area: Through precise control of the process, we can customize porosity (ranging from 30% to over 80%), pore size distribution, and pore structure to meet different fluid permeation, catalyst loading, or filtration needs.
- Outstanding chemical inertness and self-lubricating properties: Inert to most molten metals, glass melts, and corrosive gases, and not easily reactive. At the same time, it has a layered structure similar to graphite, good self-lubricating properties, and is not easily adhered to contact materials.
- Regular geometric shape: The standard rectangular shape facilitates system integration, modular design, and installation for customers, reducing subsequent processing costs.
どのような主要課題が取り組まれているのか？
Rectangular porous boron nitride ceramic blocks are key materials for addressing pain points in the following industries:
The “heat dissipation bottleneck” in high-temperature environments: Traditional metal heat sinks cannot be used in vacuum or protective atmosphere high-temperature furnaces, and insulation materials have poor thermal conductivity. This product can be used as a heat dissipation bracket or insulation screen to efficiently dissipate heat and protect sensitive components.
Pollution and loss in molten metal processing: Traditional ceramic filters introduce impurities in the melting and filtration of alloys such as aluminum, magnesium, and copper. The chemical inertness of boron nitride ensures the purity of molten metal.
Catalyst support requirements in harsh environments: In high-temperature and corrosive chemical reactions, a stable and high specific surface area support is needed. The porous boron nitride structure fits perfectly and can optimize the reaction temperature field through its thermal conductivity.
The high-power heat dissipation challenge of electronic devices: In fields such as power semiconductors and RF devices, substrates or potting materials that can both insulate and rapidly conduct heat are needed. Porous blocks can be used as thermal interface materials or as part of encapsulation structures.
