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. | |
