Zirconia and alumina crucibles (and other ceramic materials)

Zirconia and alumina crucibles

We stock high purity alumina crucibles and zirconia crucibles and other laboratory ware including various ceramic crucibles, ignition dishes, boats and lids. We can produce custom sizes and other standard ceramic materials on request. (zirconia, zircon, mullite, rare earths like yttria and hafnia, quartz, fused silica, porcelain)

We provide refractory porous crucibles for superalloys and other metals melting, precious and semi-precious melting, glass melting, etc.

Our standard range includes isostatically pressed or rammed Zirconia crucibles and a range of speciality high alumina refractory grade crucibles with high performance characteristics.

Our wide range of ceramic materials both standard and non-standard will meet your application requirements. Please discuss with us what it is you need.
