sintering magnesite in a shaft kiln - vaikuendokrinologija.lt

The natural magnesite or light-burned magnesia is calcined in a rotary kiln or shaft kiln at a temperature of 1500~2300℃ to grow and densify the magnesia crystals and transform them into almost inert sintered magnesia, also known as heavy Burnt magnesia. To achieve sintering of pure magnesite, the calcination temperature should be above 2000°C.
