When using boron nitride crucibles, the following matters need to be noted:
Temperature control:
Boron nitride crucibles have excellent high-temperature resistance, but it is still necessary to pay attention to the use temperature not exceeding its maximum operating temperature (about 1800°C in a vacuum and 2100°C in an inert atmosphere) to avoid damage to the crucible.
Avoid rapid cooling and heating:
Although boron nitride crucibles have excellent thermal shock resistance, they are prone to cracking when the temperature changes drastically, and attention needs to be paid to the heating and cooling rates.
Prevent mechanical damage:
Boron nitride materials are relatively brittle, and collisions, scratches or other mechanical damage should be avoided during use. Handle with care during transportation and cleaning.
Chemical stability:
Although boron nitride has good corrosion resistance to most molten metals and chemicals, it should be avoided from contact with strong acids, strong alkalis, and certain molten salts to prevent chemical reactions in the material.
Cleaning and maintenance:
The surface of the crucible should be cleaned in time after use to remove residues and avoid impurities from accumulating and affecting the next use. When cleaning, a soft brush or compressed air can be used to avoid scratching with hard objects.
Storage conditions:
Boron nitride crucibles should be stored in a dry, dust-free environment to avoid moisture and contamination. When not in use for a long time, it is best to place them in a dedicated protective cover.
Use environment:
The environment in which the crucible is used should avoid excessive moisture and dust, which may affect the service life and performance of the crucible.
Operation procedures:
Operate strictly following the equipment and process procedures to avoid damage to the crucible due to operating errors.
Regular inspection:
Regularly check the use of the crucible. If cracks or other damage are found, they should be replaced in time to ensure the smooth progress of experiments or production.
