Porcelain classic shaped crucibles in high, medium and low form, glazed on the inside and out, except on the bottom. Withstands temperature to 1150°C (2102°F).
- DATA MEASUREMENTS – All data measurements are typical and made at room temperature unless otherwise noted.
- THERMAL SHOCK RESISTANCE – Tests are run by quenching samples into water from various elevated temperatures. The change in temperature where a sharp decrease in flexural strength is observed is listed as ‘delta Tc’.
- CHEMICAL RESISTANCE – Although all alumina and zirconia ceramics are highly resistant to chemical attack, it is recommended that specific applications are discussed with Almath Crucibles to ensure optimum ceramic selection.
