In the process of wollastonite fining, we can forge and then cool it to protect its crystal structure which is short acicular fiber.
硅灰石微粉碎过程中，为保护硅灰石的短纤维针状结构，可在粉碎前对硅灰石进行煅烧空冷处理。
2
The crystal structure, chemical composition, physical properties and optical features of the acicular muscovite studied are the same as, or similar to, those of ordinary muscovite.
它的晶体结构、化学组成、物理和光学性质与普通白云母相同或类似，属于普通白云母。
3
With the increasing of heat input, the width of columnar crystal is increased, the dimension of acicular ferrite of weld metal is increased.
