2. Important Efficiency Comparison: Lubrication vs. Reinforcement
For overseas trade customers, the Main need for choosing components is always to match performance with application situations. The biggest difference between hBN and Si₃N₄ lies inside their functional orientation: hBN focuses on lubrication, electrical insulation, and significant-temperature resistance, whilst Si₃N₄ focuses on mechanical reinforcement, don resistance, and structural stability. The following is a detailed comparison in their critical overall performance indicators, supporting you immediately grasp the core distinctions.
2.1 Lubrication Effectiveness: hBN Has an Undisputed Gain
Lubrication overall performance may be the core advantage of hBN. On account of its layered crystal framework, the levels can slide freely underneath exterior pressure, forming a steady lubricating movie about the floor with the friction pair, which considerably minimizes friction coefficient and put on. Under different Operating ailments, hBN’s lubrication general performance demonstrates apparent positive aspects:
Below seawater lubrication disorders, the friction coefficient on the Si₃N₄-10 vol% hBN friction pair may be as little as 0.03, along with the dress in level is as little as 10⁻⁶ mm/nm. This is certainly a result of the extensive impact of hydrodynamic lubrication and boundary lubrication of your floor film fashioned by tribochemical reaction. Less than entire immersion water lubrication, the friction coefficient of your Si₃N₄-hBN/Si₃N₄ friction pair is often as low as 0.01, and that is much lower than that of pure Si₃N₄ (0.35 beneath the exact same ailments).
In contrast, Si₃N₄ has no apparent lubrication general performance. Its friction coefficient is comparatively superior (ordinarily 0.15-0.35 beneath dry friction), and it really should be employed with lubricating oil or grease in friction eventualities. Nonetheless, in superior-temperature, superior-stress, or vacuum environments wherever lubricating oil can not be made use of, Si₃N₄’s friction and dress in challenges will come to be notable, which boundaries its software in certain Distinctive lubrication scenarios.
It really is worthy of noting the addition of a little degree of hBN can Increase the densification means of Si₃N₄ composite ceramics to a specific extent, thereby improving the overall Vickers hardness, nevertheless it may even decrease the mechanical energy of Si₃N₄ to a particular extent.

For instance, during the manufacture of single crystal silicon wafers, hBN-coated graphite crucibles can face up to higher temperatures earlier mentioned 1600°C, and have superior lubrication and anti-adhesion Qualities, which can drastically Increase the yield and excellent of silicon wafers. Furthermore, hBN has fantastic electrical insulation effectiveness, and its dielectric consistent is low, that's suitable for large-temperature insulation parts in Digital gadgets.
Si₃N₄’s higher-temperature resistance is also fantastic, that has a decomposition temperature previously mentioned 1900°C. It may preserve secure mechanical Homes within the temperature number of 1200°C, but its oxidation resistance is a little inferior to hBN. When used in an oxidizing ambiance over 1300°C, a dense SiO₂ oxide movie is going to be formed to the surface of Si₃N₄, which often can avoid further oxidation of the material, but the oxide film will peel off at bigger temperatures, influencing its services lifestyle.
In terms of chemical steadiness, equally components are immune to most acids, alkalis, and organic and natural solvents. Nonetheless, hBN is not proof against powerful oxidizing acids (which include concentrated nitric acid and aqua regia) at substantial temperatures, whilst Si₃N₄ will respond with solid alkalis at higher temperatures. Consequently, when selecting materials, it is necessary to evaluate the chemical setting of the applying scenario to prevent product failure.
