Millennibond™ crucibles are truly non-wetting and have the same advantages as monolithic Zirconia crucibles but at a reduced cost.
In 2012 our objective was to develop a composite crucible suitable for super alloys that could be used to replace expensive zirconia. The application of an internal wash or coating to prevent reactions is borderline adequate for many applications. Coatings can easily de-laminate or flake off during melt cycles and result in melt inclusions that can potentially impact the quality of the cast or ingot in the case of alloy manufacturing.
Our group of ceramic and aerospace engineers focused on developing a true interlocking ceramic bond between the main crucible substrate and the inner surface layer. We trademarked this product and called it Millennibond™. These crucibles are truly non-wetting and have the same advantages as monolithic Zirconia crucibles but at a reduced cost due to the higher cost material being an external layer with a less expensive material acting as the crucible substrate.
The size and shape of the crucible is dependent upon customer requirements. Crucibles without the inside layer are also of the highest quality available. We pride ourselves on the same quality products in our general ceramic portfolio as we do on our nuclear grade products.
MillenniBOND™ crucibles are designed primarily for air and vacuum induction melting of superalloys. MillenniTEK’s innovative manufacturing process ensures precise dimensional accuracy and near-net shape crucibles. The MillenniBOND™ line of composite crucibles are alumina with an integral magnesia partially stabilized zirconia (MgO-PSZ) inside surface layer (the molten alloy contact surface). Investment casters now have the opportunity to replace costly monolithic MgO-PSZ crucibles with lower cost composite crucibles exhibiting the same non-wetting characteristics as monolithic MgO-PSZ crucibles.
MillenniBOND™ crucibles are designed primarily for air and vacuum induction melting of superalloys. MillenniTEK’s innovative manufacturing process ensures precise dimensional accuracy and near-net shape consistency. The MillenniBOND™ line of crucibles are engineered to provide a highly uniform, smooth, pits and positive free metal contact surface and excellent thermal shock and erosion resistance.
We design and build our molds in-house, resulting in reduced delivery times for custom crucibles. We can supply thick cross section high volume crucibles in a variety of materials. We also slip cast high purity alumina crucibles to any dimensional specification.
Industries we serve include copper, aluminum, superalloy, nuclear and chemical.
We also design and manufacture stopper rod type crucibles including any required graphite inserts.
