Ever heard of or used talcum powder? Talcum is made from talc minerals. It’s a naturally occurring mineral from rock formations. While talcum powder is one of the more common applications of talc, it makes up a minor portion of the mineral’s varied usage. Its unique properties make it widely used in making paint, ceramics, paper, and many others.
滑石是如何形成的？
Talc is commonly discovered in the convergent plate borders’ metamorphic rocks. In the US, for example, most of the country’s talc deposits are formed from the reaction of dolomitic marbles and dissolved silica and magnesium contained heated fluids. Talc formation may also happen when active fluids and heat come into contact with serpentinite and dunite rocks.
由于这两种形成过程，滑石具有各种颜色，包括淡绿色、蓝色、粉红色、灰色、白色、粉红色、黄白色或银色。由于人工或天然的杂质，它有珍珠般的、油腻的或暗淡的光泽
On the Mohs scale of hardness, talc’s hardness is just one. This denotes that talc is a very soft material, even the softest on earth. It is easily scratchable with a fingernail. Another characteristic of talc is that it dislikes water and won’t absorb any liquid.
Talc是如何被挖矿的？
大多数滑石都是使用露天开采或露天铸造工艺开采的，也称为大型开采。含滑石的岩石首先在这些地方钻孔，然后部分破碎成小块。
The mining process requires considerable care to prevent the talc from contaminating other minerals. Otherwise, the talc’s color may suffer due to these contaminants. Besides, contamination may make the talc pose issues in specific applications because of the mineral’s softness property.
The chunks are then sent to the mills to be crushed into smaller particles. Afterward, the particles’ impurities are removed using mechanical processing or sometimes froth flotation. Typically, the mills deliver powder or crushed talc that meets the demands of the industries.
滑石的用途是什么？
滑石矿物的最终产品已被许多人经常使用。然而，许多人仍然需要了解它的存在或它所服务的独特功能。以下是该矿物的一些常见用途：
1.陶瓷工业
滑石具有较高的耐热性；因此，这种材料被认为是制造陶瓷产品的催化剂。其中包括陶器、瓷砖、餐具、浴室固定装置等。滑石的性能提高了陶瓷材料的光学和机械质量以及釉料的外观。

2.塑料工业
与陶瓷产品一样，滑石也被用作塑料行业的填充剂。滑石颗粒的板状可以使乙烯基、聚丙烯、尼龙、聚酯和聚乙烯等塑料基材料更加坚硬。此外，它还可以减少收缩，提高这些产品的耐热性。

3.涂料行业
滑石也常用于涂料的制造，作为填料和填充剂。同样，滑石颗粒的片状使其对涂料工业有益。它改善了固体在油漆罐中的悬浮状态，并促进了其在墙壁上的应用。由于滑石颗粒具有明亮的白色，它提高了油漆的亮度和白度。

4.纸张
Paper-making industries require talc to promote paper’s smoothness. As a filling agent, talc particles are added to the pulps during the paper-making process. In this way, the particles fill in the empty spaces between the pulp molecules, giving the surface of the paper smoothness for writing.

5.化妆品行业
滑石粉在化妆品行业应用最为广泛。它的精细研磨形式用于制作涂抹在皮肤上的化妆品，可清洗而不会损坏皮肤。滑石粉具有出色的吸收能力，是一种重要的止汗添加剂。它可以吸收粘在人体皮肤上的汗液、油脂和气味。

The use of talc has not only ended there. The mineral is an additive mineral of asphaltic materials for roofing products in the US. The talc’s variety, soapstone, is applied to produce home electrical panels, countertops, figurines, etc. Moreover, its ground form is used as a lubricating agent in high-temperature manufacturing works.
从上面的阐述来看，滑石矿物与高岭土等其他矿物一样有价值。两者都用于陶瓷工业；滑石是一种添加剂，高岭土是一种基本成分。如果您的企业需要高质量的高岭土，您可以随时 联系PT Yudian Kawan Mineral—本地和全球领先的优质高岭土生产商和供应商 拥有超过30年的经验。
