Nozzles for Powder Metal Atomization

By -

Gas atomization is a kind of high efficient technique to produce high-quality metal powders. It makes the metal powders with spherical shape, clean surfaces and uniform particle sizes. And gas atomization is becoming more and more popular in modern powder production due to its high quality production.

In order to support the processing of gas atomization, INNOVACERA presents a series of atomizing nozzles including Boron Nitride and Zirconia material. We have BMA, BSC, BMZ, BAN and BSN which are all well used for metal powder’s atomization, especially BMA and BMZ are very popular. Hot pressed Boron Nitride nozzles are often used for producing nickel powder, copper powder and aluminum powder. The max working temperature is 1700- 1800℃ in vacuum.

BN atomizing nozzles

The benefits of BN atomizing nozzles
1.Non wetting make it reduce the frequency of nozzle replacement
2.Good surface finish make tolerances better
3.Very good thermal shock resistance makes BN not have to be pre-heating widely

 

Besides Boron Nitride nozzles, INNOVACERA also supplies Zirconia nozzles for powder metal atomization. This is also a very good option on material for the gas atomization. The max working temperature for the Zirconia is 2000℃ in air, vacuum or atmosphere protection environment. Zirconia nozzles are available for almost all metal and alloy powders except tungsten, molybdenum powders.

Zirconia Atomizing nozzle


The benefits of Zirconia nozzles
1.High thermal resistance make it excellent performace in high temperature atomization
2.Very good wear resistance
3.Chemical inertness make the nozzles not reactivity with atomized alloys

4.Low thermal conductivity

Boron Nitride Ceramic Insulator For High Temperature Furnace

By -
Image
  High temperature furnace designs contain heating elements made of carbon, tungsten or molybdenum. When the operating temperature of the high temperature furnace is significantly higher than 1500 ° C, the elements are electrical insulated from the furnace sides using aluminum oxide ceramics.   With the development of technology, more and more companies need high temperature electrical furnaces with shorter production cycles and faster heating and cooling speeds. These oxide ceramic insulation parts are easily subject to failure of components due to high pressure, which increases the downtime of the furnace.   Compared with traditional aluminum oxide materials, the working life of ceramic components made of hexagonal  boron nitride (BN)  is much longer. For thermal processes at extremely high temperatures and vacuum or inert conditions,  boron nitride ceramics  are often the only feasible solution. Boron nitride ceramic material max using temperature i...
