Ceramic Atomizing Nozzles
Used in the molten metal atomizing process, as well as other casting departments for flow control, Blasch atomizing nozzles are produced with the highest cast tolerances. Our ceramic and zirconia atomizing nozzles offer precise, repeatable dimensional control, assuring that each part performs exceptionally to provide precise particle sizing and flow.
Atomizing nozzles are available in several Blasch ceramic materials, including Zirconia, Oxytron™ (oxide-bonded silicon carbide), Nitron™ (nitride-bonded silicon carbide), Fused Silica, and Alumina. Zirconia atomizing nozzles are valued for their excellent thermal shock resistance and proven non-wetting characteristics, which extend campaign life in high-wear atomization environments

COMPATIBLE FERROUS AND NON-FERROUS METALS:
- Nickel and Cobalt based super alloys
- Iron, and Chromium based alloys
- Copper, Aluminum, Magnesium, and other Non-ferrous alloys
- Precious metal alloys
- Thermal spray alloys
When applications require unique compositions, our ceramic engineers can develop a custom ceramic nozzle material to best suit your process.
PROCESS APPLICATIONS FOR ATOMIZING NOZZLES:
- Vacuum Gas Atomization
- Inert Gas Atomization
- Gas Atomization
- Water atomization
CERAMIC TUNDISH ASSEMBLIES
In addition to atomizing nozzles, Blasch produces ceramic tundish components engineered for the same demanding thermal and wear conditions. Because tundish and nozzle assemblies work together to control melt flow, Blasch offers pre-assembled, fired nozzle and tundish assemblies that ship ready to install, ensuring correct atomizing tip height (stick-through) and nozzle perpendicularity right out of the box.
TESTING RESEARCH:
At our Blasch headquarters test lab, our ceramic engineers rigorously test every atomizing nozzle material to withstand the stress of thermal shock.
- Modulus of Rupture (strength testing)
- Archimedes density (density validation)
- Thermal shock resistance (rapid temperature changes)
- Creep deflection (deformation measurement)
- Corrosion resistance (oxidation resistance)
- Wear resistance (abrasion and force)
ADVANCED ENGINEERING:
For atomizing system review and new project design, our design engineers use FEA (Finite Element Analysis) to analyze material stress under varying temperatures, and CFD (Computational Fluid Dynamics) to simulate fluid flow of liquids and gases through the nozzle geometry.
CERAMIC MANUFACTURING:
Blasch's ISO 9001 quality system produces high-tolerance ceramic nozzle geometry within half a percent. An accurate fit between nozzle and mount is crucial for precise particle sizing and flow.
Blasch offers atomizing nozzle and tundish assemblies that ship directly to you. Our patented forming process was developed to produce complex-featured ceramics with unique physical properties not achievable through conventional ceramic manufacturing.
With over 40 years of experience engineering atomizing nozzles, quench nozzles, and tundish systems in ceramic, zirconia, and silicon carbide materials, Blasch's sales engineers are ready to discuss your application.
