1. Handle the boats carefully: Boron nitride boats are fragile and can easily break if mishandled. Avoid dropping or hitting them against hard surfaces.

2. Keep the boats clean: Clean the boats thoroughly before use to avoid any contamination that may affect the deposition process.

3. Use proper evaporation conditions: Choose appropriate heating rates and deposition temperatures to optimize the evaporation process. Boron nitride boats can withstand high temperatures up to 2000 degree .

4. Avoid overloading the boats: Do not overload the boats with materials as it may result in a non-uniform deposition.

5. Use appropriate crucibles: Boron nitride boats are typically used for thin film deposition in vacuum conditions. If you need to use the boats in other environments, make sure to choose appropriate crucibles for your application.

By following these simple tips, you can use boron nitride boats for evaporation safely and effectively. They are a great solution for high-temperature vacuum deposition processes due to their excellent thermal and chemical stability. With proper care and handling, boron nitride boats can offer reliable and repeatable results and can help you achieve your desired outcomes.
