Boron Nitride Ceramic Parts
The hexagonal boron nitride ceramic crucible is made by grinding the hot-pressed boron nitride ceramics with hard alloy tools.
Description
Boron nitride ceramic part is made by grinding the hot-pressed boron nitride ceramics with hard alloy tools.
Due to the unique chemical and thermal stability of hexagonal boron nitride, boron nitride ceramics will not react or adhere to most metal liquids, and will not affect its performance under high-temperature environments. Therefore, it is suitable for processing into crucibles, precision parts, or nozzles for the metallurgical industry.
Boron nitride ceramics are widely used in high-temperature insulating parts, atomic energy, metallurgy, aviation, and other fields because of their high thermal conductivity, good electrical insulation properties, low thermal expansion coefficient, and non-wetting properties with most metals.
Boron nitride ceramic materials have excellent machining properties and can be machined into complex shapes with minimal tolerances as required.
Note: Boron nitride should always be kept dry in an airtight bag or in a drying oven to prevent moisture.

QUALITY CONTROL
Before each batch of ceramic parts is packed, there will be special personnel to spot check and measure the size, making sure that the size is close to the drawings to the maximum extent within the tolerance range. As shown in the figure below.
WAY OF PACKING
In order to prevent the ceramic parts from being bruised and damaged, we mostly use foam cotton to pack the ceramic parts independently and then put the packed ceramic parts into sealing bags for sealing. As shown in the figure below.
