  Boron Nitride Nozzles for Molten Metal Atomizing Boron Nitride nozzles  are widely used in the processing of metal powder. Molten metal atomization is a process used to fabricate metal powder from a melt. In a typical atomizer, liquid metal is poured from a nozzle into a large chamber while being sprayed with high-pressure water, oil or gas. This causes the metal droplets to separate and condense into a powder that collects at the bottom. Atomization has become one of the most popular methods of powdering metals. Atomization begins in a furnace where the metal is kept liquefied by electric heating elements. The metal falls into the spray chamber through a “nozzle” – this nozzle is designed to a high degree of perfection and specification. The nozzle is one of the most important parts of the atomization process – a damaged or clogged nozzle can cause the metal flow to stop or the flow to increase dramatically – both of which can disrupt the powdering process. To prevent this ...

The most commonly used forming processes in the   advanced ceramics industry  are cold isostatic pressing, injection molding, hot isostatic pressing and dry pressing. As an advanced ceramics manufacturer, we’d like to introduce the cold isostatic pressing process. CIP is a method of compacting powdered materials into a solid homogeneous mass before machining or sintering. It can produce high-integrity billets or preforms that exhibit little distortion or cracking when fired. Its advantages and features include: Improve production efficiency:  CIP is easy to operate, the process is stable and can be mass-produced, so the production efficiency is high. Optimizing material properties:  CIP can make the powder material form a dense green body under high pressure, which has a high density, usually reaching more than 95% of the theoretical density. This makes the ceramic material produced by cold isostatic pressing have higher strength, hardness and wear resistance. Fine g...
