二氧化鈦1
 
二氧化鈦存在著三種晶型,即板鈦礦、銳鈦礦及金紅石晶型。雖然在陶瓷生產知識中,我們認為它是著色元素,實際上,在自然界中,二氧化鈦是自然產出算是比較白的礦物。鈦白粉的名字就表明其特色就是白。而之所以二氧化鈦在陶瓷生產中被認為是著色元素,對生產不利,主要是因為二氧化鈦在800℃之后,發生晶型轉變,變成了帶顏色的晶型,從而著色。而在我們陶瓷生產中,往往溫度高達1000多℃,因此,在很多行業里表現優異的二氧化鈦在陶瓷行業成了不利的因素。
There are three crystal types of titania, namely, perovskite, anatase and rutile. Although in ceramic production knowledge, we think it is a coloring element, in fact, in nature, titanium dioxide is natural output is a relatively white mineral. The name of titanium dioxide indicates that it is white. The reason why titanium dioxide is considered as a coloring element in the production of ceramics is unfavorable to production, mainly because of the crystalline transformation of titanium dioxide at 800 degrees C, which turns into a color crystal, thus coloring. In our ceramic production, the temperature is often as high as more than 1000 degrees C, so the titanium dioxide in many industries has become an unfavorable factor in the ceramic industry.
在近幾年的陶瓷生產過程中,在比較開始的時候,陶瓷原料對于鐵鈦元素基本上是采取嚴防的策略,以防止著色。但慢慢開始出現一些轉變,個別陶瓷公司對一些產品生產所需原料開始放寬鐵鈦的進廠標準。如長石中的鐵含量從0.15%放大到0.2~0.4%,而鈦的含量也從0.1%以內放大到0.2~0.3%以內。主要是考慮到鐵鈦可以發生反應,產生的顏色化合物對于一些產品恰好相符。
In recent years, in the ceramic production process, at the very beginning, ceramic raw materials were basically taken precautions against iron and titanium elements to prevent coloring. However, some changes began to take place. Some ceramic companies began to relax the entry standards of titanium and titanium for the production of some products. For example, the iron content in feldspar is increased from 0.15% to 0.2~0.4%, and the content of titanium is enlarged from 0.1% to less than 0.2~0.3%. It is mainly considered that iron and titanium can react, and the color compounds produced are exactly the same for some products.
除此以外,在陶瓷行業,二氧化鈦應該具有更大的應用空間,讓人們主動去用鈦而不是防鈦。這個就是二氧化鈦產品所對應的自潔凈產品。顧名思義,通過合理的工藝,在陶瓷產品表面制備上一層二氧化鈦薄膜,可以讓陶瓷產品產生自潔凈效應,非常適合外墻和衛生間陶瓷產品。
In addition, in the ceramic industry, titanium dioxide should have greater application space, enabling people to take the initiative to use titanium instead of titanium. This is the self cleaning product corresponding to titanium dioxide products. As the name suggests, a layer of titanium dioxide film is prepared on the surface of the ceramic product by reasonable technology. It can make the ceramic product self clean and suitable for the ceramic products of the exterior wall and toilet.
