金红石型钛白粉he锐钛型钛白粉有什么区别？
1）内部结构晶体
1) internal structure crystal
钛白粉共有三种不同的晶体结构，即我们常说的金红石型钛白粉、锐钛型钛白粉、板钛型钛白粉，三者晶体结构各不不同，其中金红石型钛白粉晶体结构最为稳定；而板钛型钛白粉则用途非常少，这主要是由于它内部结构晶体的不稳定，因此在自然界就没办法可以长期稳定的保存起来，没有生产使用价值；
Titanium dioxide has three different crystal structures, we often say that the rutile titanium dioxide, titanium dioxide anatase type titanium plate, titanium dioxide, three crystal structure of the different, the rutile titanium dioxide crystal structure is the most stable; and titanium plate type titanium dioxide is the use of a very few, this it is mainly due to the internal structure of the crystal is not stable, so there is no way in nature can be long-term preserved, no production value;
由于金红石型产品晶型更趋向六面体，比较锐钛更容易分散均匀，其所形成的团聚物更加均匀。粒径分布更为窄。
As the rutile type products tend to be more hexahedron, the sharp titanium is more easily dispersed and homogeneous, and the agglomeration is even more uniform. The particle size distribution is narrower.
2）熔点和沸点
2) melting point and boiling point
由于锐钛型在高温下会转变成金红石型，因此锐钛型二氧化钛的熔点和沸点实际上是不存在的。只有金红石型二氧化钛有熔点和沸点，金红石型二氧化钛的熔点为1850℃、空气中的熔点为(1830±15)℃、富氧中的熔点为1879℃，熔点与二氧化钛的纯度有关。金红石型二氧化钛的沸点为为(3200±300)℃，在此高温下二氧化钛稍有挥发性；
Due to the sharp titanium type will be transformed into rutile at high temperature, so the melting and boiling of anatase titanium dioxide is not in existence. Only rutile TiO2 has melting point and boiling point. The melting point of rutile titanium dioxide is 1850 degrees, the melting point of air is (1830 + 15), the melting point of oxygen is 1879 degrees, and the melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium dioxide is (3200 + 300) C, and the titanium dioxide is slightly volatile at this high temperature.
3）介电常数
3) dielectric constant
由于二氧化钛的介电常数较高，因此具有优良的电学性能。在测定二氧化钛的某些物理性质时，要考虑二氧化钛晶体的结晶方向。锐钛型二氧化钛的介电常数比较低，只有48。
Due to the high dielectric constant of titanium dioxide, it has excellent electrical properties. In the determination of some physical properties of titanium dioxide, the crystal direction of titanium dioxide should be considered. The dielectric constant of anatase titanium dioxide is low, only 48.
4）电导率
4) electrical conductivity
二氧化钛具有半导体的性能，它的电导率随温度的上升而迅速增加，而且对缺氧也非常敏感。金红石型二氧化钛的介电常数和半导体性质对电子工业非常重要，可利用该性质生产陶瓷电容器等电子元器件。
Titanium dioxide has the properties of semiconductors, and its conductivity increases rapidly with the rise of temperature, and is also very sensitive to oxygen. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important for the electronics industry, which can be used to produce electronic components such as ceramic capacitors.
5）硬度
5) hardness
按莫氏硬度十分制标度，金红石型二氧化钛为6～6.5，锐钛型二氧化钛为5.5～6.0，因此在化纤消光中为避免磨损喷丝孔而采用锐钛型。
According to Mohr's hardness, the rutile TiO2 is 6 to 6.5, and the anatase titanium dioxide is 5.5 to 6. Therefore, in the chemical fiber extinction, the sharp titanium is used to avoid wearing the spinneret.
6）生产方法
6) production method
虽然金红石与锐钛硫酸法生产的工艺基本类似，但是具体参数存在很大的差别。锐钛产品大多用硫酸法进行生产，但是金红石产品现在有硫酸法与氯化法两种。
Although the process of rutile and anatase sulfuric acid method is basically similar, the specific parameters are very different. Most of the products are used in the production of anatase rutile sulfuric acid method, but the products now have two kinds of sulfuric acid method and chlorination.
7）包膜
7) coating
锐钛产品基本在煅烧结算，经过雷蒙磨破碎之后进行包装销售，而金红石产品为了更好的提高其分散，耐候等特性，在煅烧后使用氧化铝或者锆进行表面处理，帮随同时的还有进行部分的有机处理。
The anatase products in the calcination settlement, after crushing Raymond Mill packaging sales, while the rutile products in order to improve its dispersion, weather resistance, surface treatment using alumina or zirconia after calcination, with the help and the organic part of.
8）价格
8) price
通过生产方式不难看出，金红石型的钛白粉成本比锐钛型的高，售价自然也高，目前来看，金红石型钛白粉售价大约比锐钛型钛白粉高3000-4000元每吨。
It is not difficult to see that the rutile titanium dioxide cost is higher than that of anatase and its price is high. At present, rutile titanium dioxide sells for about 3000-4000 yuan per ton of titanium dioxide.
另外，A型二氧化钛白度较好，但着色力仅为R型的70，在耐候性方面加入A型二氧化钛试片仅仅经过一年以后即开始龟裂或者碎片状剥落，而加入R型二氧化钛试片，经过十年以后其外观只有很小变化。由于R型二氧化钛着色力及耐候性较佳，塑料着色使用R型二氧化钛为好。
In addition, A type titanium dioxide whiteness is good, but the color force is only R type 70, A type titanium dioxide in joining the weather resistance test pieces after only a year later began cracking or fragmented spalling, while adding R type titanium dioxide specimens after ten years after the appearance of only a small change. Because of the better coloring force and weatherability of R titanium dioxide, the plastic coloring is good for the use of R titanium dioxide.
按照钛白粉的制造工艺目前有硫酸法和氯化法，两种方法都可生产A型和R型钛白粉。硫酸法于1931开始，氯化法由美国杜邦公司于1975年才开始生产A型，氯化法中氧化步骤控制粒子大小分布和晶体结构，使其可以生产具有高遮盖力和底色兰，高着色强度的钛白粉。
According to the manufacturing process of titanium dioxide are sulfuric acid and chloride, two kinds of methods can produce A type and R type titanium dioxide. Sulfuric acid method in 1931 started, chlorination by DuPont Co began in 1975 the production of A type oxidation step control, particle size distribution and crystal structure in the chlorination, which can produce high hiding power and bottom color, high tinting strength of titanium dioxide.
近期，钛白粉产业如火如荼，行业升温，希望我国的钛白粉生产在未来能够突破技术壁垒，生产出高品质的钛白粉。同时目前行业乱象普遍，希望生产厂家减少牌号、明确标识技术参数、使用标准中文包装，防止假冒伪劣掺混产品横行市场！
In recent years, titanium dioxide industry is booming, and the industry is heating up. I hope our titanium dioxide production will break through technical barriers in the future and produce high quality titanium dioxide. At the same time, the industry chaos is widespread. It is hoped that the manufacturer will reduce the brand number, clearly identify the technical parameters, and use the standard Chinese packaging, so as to prevent counterfeit and shoddy products from going all the way.
