For overseas trade potential buyers, the core need for choosing products will be to match effectiveness with application eventualities. The most significant difference between hBN and Si₃N₄ lies in their purposeful orientation: hBN focuses on lubrication, electrical insulation, and superior-temperature resistance, when Si₃N₄ focuses on mechanical reinforcement, have on resistance, and structural security. The following is a detailed comparison in their crucial overall performance indicators, encouraging you speedily grasp the Main variances.
two.1 Lubrication Effectiveness: hBN Has an Undisputed Advantage
Lubrication effectiveness will be the core benefit of hBN. Because of its layered crystal framework, the levels can slide freely under external power, forming a steady lubricating movie over the surface area with the friction pair, which significantly decreases friction coefficient and don. Less than various Doing work disorders, hBN’s lubrication overall performance exhibits clear strengths:
Underneath seawater lubrication disorders, the friction coefficient of the Si₃N₄-ten vol% hBN friction pair is usually as little as 0.03, as well as don level is as little as 10⁻⁶ mm/nm. This can be as a result of extensive impact of hydrodynamic lubrication and boundary lubrication from the surface movie formed by tribochemical response. Underneath whole immersion water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair is usually as little as 0.01, which can be far lessen than that of pure Si₃N₄ (0.35 beneath the identical conditions).
In distinction, Si₃N₄ has no apparent lubrication performance. Its friction coefficient is fairly higher (ordinarily 0.fifteen-0.35 beneath dry friction), and it should be utilized with lubricating oil or grease in friction situations. Nevertheless, in superior-temperature, large-tension, or vacuum environments in which lubricating oil can not be utilized, Si₃N₄’s friction and use problems will turn into popular, which limits its application in a few Exclusive lubrication eventualities.
It's value noting which the addition of a little degree of hBN can improve the densification process of Si₃N₄ composite ceramics to a certain extent, thereby strengthening the overall Vickers hardness, but it surely will also lessen the mechanical toughness of Si₃N₄ to a specific extent.

In addition, hBN has excellent electrical insulation performance, and its dielectric regular is small, which happens to be suited to substantial-temperature insulation components in Digital units.
Si₃N₄’s higher-temperature resistance is also fantastic, by using a decomposition temperature over 1900°C. It can retain stable mechanical Houses inside the temperature range of 1200°C, but its oxidation resistance is a little inferior to hBN. When used in an oxidizing environment above 1300°C, a dense SiO₂ oxide film are going to be shaped within the floor of Si₃N₄, which may protect against additional oxidation of the material, although the oxide movie will peel off at greater temperatures, impacting its assistance life.
Regarding chemical steadiness, both components are proof against most acids, alkalis, and organic and natural solvents. Having said that, hBN is not resistant to powerful oxidizing acids (including concentrated nitric acid and aqua regia) at substantial temperatures, when Si₃N₄ will respond with sturdy alkalis at significant temperatures. Hence, when selecting materials, it's important to evaluate the chemical ecosystem of the applying circumstance in order to avoid materials failure.
