钛白粉的主要成分是TiO2,化学性质稳定，在一般情况下与大部分物质不发生反应。在自然界中二氧化钛有三种结晶：板钛型、锐钛型钛白粉和金红石型钛白粉。板钛型是不稳定的晶型，无工业利用价值，锐钛型钛白粉(Anatase)简称A型，和金红石型钛白粉(Rutile)简称R型，都具有稳定的晶格，是重要的白色颜料和瓷器釉料，与其他白色颜料比较有优越的白度、着色力、遮盖力、耐候性、耐热性、和化学稳定性，特别是没有毒性。

The main component of the titanium white powder is TiO2, which is stable in chemical properties and does not react with most of the material in general. There are three kinds of titanium dioxide in nature: titanium plate type, anatase titanium white powder and rutile titanium white powder. Titanium plate type crystal is not stable, no industrial utilization value, anatase titanium dioxide (Anatase) referred to as A, and rutile titanium dioxide (Rutile) referred to as R, have the stability of the lattice, is an important white pigment and glaze porcelain, compared with other white paint has excellent whiteness. Tinting, covering power, weatherability, heat resistance, and chemical stability, especially there is no toxicity.

钛白粉兼有锌白的持久性和铅白的遮盖性,是高档白色颜料，最大的优点是无毒，在高级化妆品中作为增白剂。其覆盖能力强，折射率高，也用来做高级白色油漆。也可用作高级铜版纸的表面覆盖剂，以及用来生产增白尼龙。陶瓷中加入可以提高陶瓷的耐酸性。钛白还具有半导体性能，以其无毒、价廉、催化活性高的特点，成为多项光催化反应中最常用的半导体材料。还可用作乙醇脱水,脱氢的催化剂。

Covering both the durable titanium dioxide and zinc white, high-grade white pigment, the biggest advantage is non-toxic, as whitening agent in senior cosmetics. With high coverage and high refractive index, it is also used for high level white paint. It can also be used as a surface covering agent for advanced copperplate and the production of whitening nylon. The acid resistance of ceramics can be improved by the addition of ceramic. Titanium dioxide is also the most commonly used semiconductor material in a number of photocatalytic reactions because of its non-toxic, low price and high catalytic activity. It can also be used as a catalyst for dehydration and dehydrogenation of ethanol.
