To avoid failure, operators must implement a gradual power ramp-up to allow the intermetallic material to expand uniformly and shed any latent moisture without internal pressure buildup. It is essential to achieve full thermal equilibrium where the boat exhibits a consistent, bright glow.
Reuse of the evaporation boats is possible, though it is highly contingent on their physical condition. As long as the boats remain free of cracks or material buildup, they can stay in service. However, any signs of performance degradation suggest they should be replaced. Since actual lifespan varies based on specific application requirements, we recommend regular inspections and the use of approved cleaning protocols to maximize longevity. Please contact us for tailored technical guidance.
When heated or cooled too rapidly, the BN boat’s internal stresses exceed the material’s mechanical strength, leading to the fractures. Besides, boron nitride is naturally hygroscopic. Trapped water turn into steam instantly at high temperatures, causing the crack from the inside out.
Boron nitride is very sensitive to the humidity of the surrounding environment. Therefore, the boats should be stored in their original vacuum-packed containers until installation. Should the package be broken, they can be stored in an environmentally controlled setting or desiccator cabinet. A drying cycle is well advised if the boats have had time to absorb humid air.
For maximum life, please keep a minimum number of heating and cooling cycles. Start-stop cycles will subject the material to cyclic expansion and contraction, thus shortening the life of the material.
