“Imperial Porcelain” ceramic balls for stoves are made of special mullite-corrundum porcelain. This porcelain is 90% alumunium oxide Al2O3, which is the knowingly hard corrundum.

·         Imperial Porcelain has a Mohs hardness of 9 and is therefore second only to diamond.

·         Its operating temperature is 1650°C, which is almost twice that of jadeite.

·         Its heat capacity is comparable to that of jade and reaches up to 1.1 kJ/(kg°С)

Thanks to these properties, ceramic balls do not crack and do not change in color due to prolonged exposure to cyclical temperature drops.


Density: 3700 kg/m3.

Specific heat capacity: 1,1 kJ/kg°C

Compressive strength: 3000 to 4000 MPa


Melting point: 2050 °C
