金红石型要比锐钛型的耐粉化性、保光性好。然而，纯 TiO2(锐钛型二氧化钛)颗粒表面在有水汽和氧气的存在下是光化学活泼的，而非生来就是光化学稳定的。纯TiO2甚至可促进在其颗粒周围基料的降解。因此有必要首先将TiO2本身光稳定化。该稳定性的大小可以通过对其进行不同无机氧化物的种类及份量控制而得。即对 TiO2进行无机包膜处理。使在TiO2颗粒周围表面和有机树脂之间形成一道屏蔽网不再促进(减少)有机树脂的降解。 Ti—Pure? R—706和 R—96O是这一类钛的杰出代表物。他们周围都有非渗性致密 SiO2表面包膜。这些 SiO2包膜能够提供最强大的光化学保护性和稳定性。
The rutile type is more powdered and light - preserving than the anatase type. However, the surface of pure TiO2 (anatase titanium dioxide) particles is photochemically active in the presence of water vapor and oxygen, rather than photochemical stability. Pure TiO2 can even promote the degradation of the base material around its particles. Therefore, it is necessary to stabilize the light of TiO2 first. The size of the stability can be controlled by the variety and weight of different inorganic oxides. That is, TiO2 is treated with inorganic coating. The formation of a shielding net between the surface of the TiO2 particles and the organic resin no longer promotes (decrease) the degradation of organic resin. Ti - Pure? R - 706 and R - 96O are outstanding representatives of this type of titanium. They all have an impermeable dense SiO2 surface envelope around them. These SiO2 coatings provide the most powerful photochemical protection and stability.
无论是金红石型还就是锐钛型钛白粉，在可见光波长范围内(400—700nm)、它们对光线的反射率都很高，因而都具有很好的白度。但是在小于可见光范围如300—400纳米的紫外光波长范围内，两种不同晶型的所表现出的性能却有着很大的差别。对于金红石(红线)在具有很强杀伤力的 UV—A波段内(350—400nm)它对紫外线的反射率要远远低于蓝色的锐钛型，换句话说、它对紫外线的吸收率要大大地高于蓝色的锐钛型。在这种情况下，它周围的成膜物有机树脂身上所要分担的紫外光线就要少得多。
Rutile type is also anatase titanium dioxide. It has good whiteness in visible wavelength range (400 to 700nm) and high reflectivity to light. But within the range of UV wavelengths less than 300 to 400 nanometers, such as the visible light range, the performance of the two different crystalline forms is very different. For Jin Hongshi (red line), it has a very strong lethality in the UV A band (350 - 400nm). Its reflectivity to ultraviolet is far lower than that of blue anatase. In other words, its absorption rate to ultraviolet is much higher than that of blue anatase. In this case, there is much less ultraviolet light to be shared by the organic resin around it.

了解了以上金红石型钛白粉与锐钛型钛白粉性能区别后，其实在它们的应用过程中，还有一点应该考虑到的，椐笔者这么多年从事钛白粉销售中了解到，生产厂家在用钛白粉的时候，在成本问题上用那一个也有想法的。金红石型钛白粉大部分都是生产高档的产品。好像说：生产涂料用钛白粉 油墨用钛白粉 塑料漆 木器漆 以及高档的印花胶浆一定会选用金经石型钛白粉。只有是金红石型钛白粉才能给高档产品漂亮的遮盖力。高的光泽度。分散过程中，也会省时省力。
To understand the properties of rutile titanium dioxide and titanium dioxide anatase difference, in fact, in the process of their application, one point should be taken into account, according to the author for so many years engaged in titanium dioxide sales to manufacturers when using titanium dioxide, thought to have the one on the question of cost also the. Most of the rutile titanium white powder is the production of high grade products. As if to say: the production of coatings with titanium dioxide ink with titanium dioxide plastic wood paint and high-grade printing paste will be selected from gold type titanium dioxide. Only rutile titanium white powder can give high quality products a beautiful covering power. High glossiness. In the process of dispersing, it will save time and effort.

在市场上来说：生产塑料/ 水墨/ 大众化印花胶浆/ 年画/ 涂布等行业中。锐钛型钛白粉还是很吃香的。锐钛型钛白粉价格底，也有一定的白度，只不过是在生产中，要研磨，有或者是经高温技术生产让锐钛型钛白粉分散力强点，才能达到理想的状态。所以说：两者也占有一定的市场。
In the market, the production of plastic / ink / mass printing paste / annual painting / coating industry. Anatase titanium dioxide is still very delicious. Anatase titanium dioxide prices at the end of a certain degree, but is in production, to grind, or by high technology for the production of anatase titanium dioxide dispersion force strengths, to achieve the ideal state. Therefore, they also occupy a certain market.
就是说：你是生产什么东西。就用什么产品高档点的用金红石型钛白粉，中低档的就可以用锐钛型钛白粉。两者中你们来选择而已。
That is to say: you are producing what. On the top of the product, the use of rutile titanium white powder, middle and low grade titanium white powder can be used. You have to choose both of them.
