SILICON CARBIDE CRUCIBLES & GRAPHITE CRUCIBLES

These graphite and silicon carbide crucibles have high temperature resistance, anti-oxidation, corrosion resisting, abrasion resistance, good conductivity and good thermal efficiency and are ideal ceramic substitutes. Suitable for melting metals such as copper, gold, silver, zinc, aluminium, lead... Mainly used in the various powder sintering and metal smelting in the fields of metallurgy, chemical industry and glass, and used as the dewatering and various grinding elements.
Graphite crucibles and silicon carbide crucibles are available in many dimensions - ask.

ZIRCONIA CRUCIBLES

Standard production refractory grade Zirconia crucibles

Refractory grade zirconia crucibles are made of calcium-stabilised or yttria-stabilised zirconia.

Zirconia crucibles (ZrO2) withstand temperatures up to 2400°C, they are chemically very inert, highly resistant thermal shock, non-conductive and corrosion resistant to acids and alkalies when compared with porcelain crucibles. Zirconia crucibles are ideal for melting of precious metals and super-alloys, and they will not react with molten aluminium, iron, nickel, platinum, silicate and acid slag - to name a few. They may be used to make crucibles for smelting of precious and other metals, heat resistant enamel, refractory pipe, glass, induction melting crucibles for specialist steel, smelting and refining.


"Yttrium oxide, also known as yttria, is Y2O3. It is an air-stable, white solid substance." - Wikipedia
"Yttria-stabilised zirconia (YSZ) is a ceramic in which the crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide." - Wikipedia

"A few percent of the oxides of calcium or yttrium stabilise the cubic crystal phase." - Wikipedia
