Product Description Product Description Kamtai Ceramics offer a range of Zirconia ceramic based products. All products are manufactured to exacting standards with unique properties. This puts our product range at the forefront of performance.

Examples include metering nozzles (flow control nozzles) which are used for the continuous casting of steel as well as zircon atomizing nozzles for use in the Powder Metallurgy industry.

We also offer a range of crucibles based upon stabilised Zirconia. The properties of the finished product are determined by both the manufacturing method and the choice of the stabilising media.

Properties of zirconia ceramic nozzles
* Long and Extended Casting Sequence Times
* Controlled and Stable Casting Speed
* Resistance to Oxygen lancing
* Consistent Re-stranding
