摘要： A minute-particle iron oxide red pigment slurry is formed by adding sodium silicate to a minute-particle iron oxide red pigment slurry, and used to form a red filter formed between a phosphor layer of a color cathode ray tube and a panel thereof. Therefore, even if the red filter is brought in contact with a black matrix under the condition of a process of manufacturing the color cathode ray tube at high temperature, the red filter does not discolor the black matrix.

摘要： A low brightness pigment and method is provided from a heretofore rejected waste kaolin stream. Kaolin processing rejects are high in iron-stained TiO.sub.2. After separating the stained TiO.sub.2 from the high brightness kaolin and concentrating the resulting fraction, the material can be processed to produce a low brightness pigment suitable of many applications where lower brightness is desirable, such as coating paper board without mottling.

摘要： A method of increasing the hydrophobicity of solid materials. The inventive method comprises the steps of: (a) metal ion activating the surface of a solid substrate material to provide reactive metal sites on the surface and (b) chemically bonding a surfactant to the surface at the reactive metal sites. Titanium dioxide pigments and other particulate property modifiers treated in accordance with the inventive method are more readily dispersed in polymer compositions.

摘要： The invention relates to a method for the preparation of transparent metal oxide pigment, in which a substantial portion of the silicon oxide is dissolved off from silicon dioxide based particles coated with transparent metal oxide, and to a transparent metal oxide pigment prepared by the method. In the extraction methods according to the prior art the problem is that in the extraction a part of the metal oxide is also dissolved, whereby thickness variations impairing the interference color of the metal oxide layer are created. Moreover, in the known methods hard-treated extraction chemicals which are detrimental for the environment are used. These problems have by means of the present invention been solved so that such particles are selected for the dissolution whose silicon dioxide portion is substantially soluble in base and metal oxide portion is substantially insoluble in base, and the dissolution is carried out by base. The silicon dioxide based particles can be selected from the beginning base-soluble particles or they can be made base-soluble by extracting them with mineral acid. The shape of the metal oxide particles obtained through base extraction corresponds fragmentarily to the form of the outer surface of the silicon dioxide based particles and they are in the form of single closed sheets or flakes.
摘要翻译：本发明涉及一种制备透明金属氧化物颜料的方法，其中大部分氧化硅从涂覆有透明金属氧化物的二氧化硅基颗粒溶出，并且通过该方法制备的透明金属氧化物颜料。在根据现有技术的提取方法中，问题在于，在提取中，金属氧化物的一部分也溶解，从而产生损害金属氧化物层的干涉色的厚度变化。此外，在已知的方法中，使用对环境有害的硬处理提取化学品。通过本发明的这些问题已被解决，使得这些颗粒被选择用于其二氧化硅部分基本上可溶于碱的溶解，金属氧化物部分基本上不溶于碱，并且通过碱进行溶解。基于二氧化硅的颗粒可以从初始的可溶性颗粒中选择，或者可以通过用无机酸提取它们而使其易溶于碱。通过碱提取获得的金属氧化物颗粒的形状与二氧化硅基颗粒的外表面的形式不相符，并且它们是单一封闭的片或薄片的形式。
