Abstract:
Perlite is volcanic glass of amorphous aluminum silicate, mainly composed SiO
2 and Al
2O
3, and has high expansibility due to its inclusion of crystalline water. Perlite is mainly used to prepare expanded perlite with a wide application field. The structural properties, resources status and application in strategic emerging industry of perlite were introduced, and the development gap of perlite industry at home and abroad was summarized. The development strategy of perlite industry in China was forecasted.
