Applications:
1. Building material industry:
| The needle-like
wollastonite powder, which has a high length-diameter
ratio,is gradually replacing the harmful asbestos.
Because wollastonite powder can remain its needle-like
structure even after special processing ,the ability of
shock resistance,crook-resistance and wearability of
materials such as calcium silicate board,fireproofing
board,etc. will be highly enhanced if proper amount of wollastonite powder was added in it.
We can predict that the wollastonite will be more widely
used in construction material area in the near future. |

2. Friction material industry:
| The needle-like
wollastonite powder is the most suitable material for
friction products. Its substituting of expensive fiber material
can directly leads to lower cost and higher economic efficiency.
At the same time, its unique mechanical performance in
physics can obviously increase the ability of resisting
friction and heating of the products. So it can be used
into clutch, pulley, abrasive paper etc. |

3. Ceramic industry:
| Adding the
right amount wollastonite powder in ceramic raw materials
can reduce the temperature of burning and shorten the
time of burning and achieve the burning of ceramic with
only one time. Mean while it can also economize the fuel
using and cost cutting in making ceramic products. The
qualified rate of the products will be increased obviously
by using wollastonite powder in ceramic industry . Because
it can improve the mechanical features, reduce the crack
and warp, enhance the intensity and glossiness of the
glaze of the ceramic products. |
