摘要
The process of preparing wollastonite ultrafine powder by impact smashing method is investigated in order that the product’s size can reach to micrometre grade and aspect ratio over 10∶1,and hence satisfy the application demand as fibre filler in industry. The results show that the aspect ratio of the wollastonite ultrafine powder manufactured by impact smashing method is 10.86:1,and the key of increasing the aspect ratio is to raise the probability of selective smashing in smashing zone.
