Inorganic pigments are almost exclusively based on oxide, oxide hydroxide, sulfide, silicate, sulfate, or carbonate and can be classified into four main groups: white pigments, black pigments carbon black , colored pigments, and specialty pigments. Heubach focuses on the production and development of colored inorganic pigments, especially complex inorganic colored pigments CICPs and encapsulated bismuth vanadate pigments.

List of inorganic pigments

Mixed Metal Oxide Pigment. Natural Iron Oxide Pigments. Organic vs Inorganic Pigments. Phthalocyanine Pigments. Synthetic Iron Oxide Pigments.

Organic vs Inorganic Pigments

Pigments are usually dispersed in vehicles or substrates for application, as for instance in the manufacture or inks, paints, plastics or other polymeric materials. Pigments retain a crystal or particulate structure throughout the coloration process. Pigment can be classified into organic pigments, inorganic pigments, organic pigments which can be divided into azo pigments and non-azo pigments, as picture 2 below. The non-azo pigments can further subdivide into pigments such as heterocyclic and fused ring including phthalocyanine, quinacridone, perylene and perinone, thioindigo, anthraquinone, dioxazine, isoindolinone and isoindoline, diketo-Pyrrole-pyrrole DPP , triarylcarbonium, quinophthalone. Inorganic pigments include titanium dioxide white, carbon and plant black, iron oxide, cadmium, lead chromate, chromium oxide green, ultramarine blue, iron blue, chrome green, phthalocyanine green, mixed metal oxides, bisovanadates, Manganese oxide MNO. Compared with organic pigments , inorganic pigments have lower cost, simple production process and higher yield than organic pigments.

Dyes are extensively used for coloring and there are many places of their applications. Right from the colors on your t-shirts and garments to the color in your foods — dyes and pigments are significantly used. When talking of pigments, there are organic pigments and inorganic pigments available in the market. Both varieties are used in different industries and come with their own set of pros and cons. Pigments are nothing but organic or inorganic insoluble coloring materials.

Organic pigments are formed from complex carbon chemistry and are synthetically derived in laboratories. Most organic pigments offer high chroma, high tinting strength and exceptional transparency. A transparent organic pigment, like a small piece of stained glass, allows light to pass through practically undisturbed. This characteristic allows mixtures with relatively high brilliance and clarity. Inorganic pigments are not based on carbon chemistry, but instead are derived from natural minerals or ores. These materials are oxides, sulfides, or various slats of metallic elements. Examples include iron oxide, cadmium sulfides and titanium dioxides.


Organic and inorganic pigments are types of pigments based on their method of formulation. Organic pigments are generally derived from plants.


Difference between Organic Pigments and Inorganic Pigments

Legislation in various parts of the world is making life difficult for those engaged in the process of coloration, whether they are in the paint, printing ink or plastics industries. Traditionally one has used organic pigments where high colour strength, bright shade and transparency were required, while using inorganic pigments for opaque full shades and good heat stability.

The book provides a complete overview on inorganic pigments and their use in dye industry. Each chapter introduces a certain class of pigment in respect of fundamentals, manufacture, properties and toxicology and thus being very valuable for paint chemists and materials specialists. The readers will benefit from a concise and well-structured text, numerous examples and a set of test questions in the end of each chapter. A comprehensive overview of all main types of inorganic pigments. Each chapter has a uniform structure based on a certain type of pigment.

Raw material science plays a big part in the quality of our products and our reputation in the industry. Since color is one of our core competencies, pigments are a very important material category. Both play an important part in the world of colorants and both become an integral part of our color concentrates.

Colors are an important part of our daily lives. From the clothing, cosmetics, and decorations we surround ourselves with to the foods we eat and how we communicate, color is an essential part of life, serving both aesthetic and functional purposes. As such, manufacturing colors is an important part of industry —but, how is color produced?

Heubach’s Inorganic Pigments

Хотя Стратмор терпеть не мог выделять кого-нибудь из подчиненных, он с особым вниманием относился к своей единственной сотруднице. Когда его обвиняли в фаворитизме, он в ответ говорил чистую правду: Сьюзан Флетчер - один из самых способных новых сотрудников, которых он принял на работу. Это заявление не оставляло места обвинениям в сексуальном домогательстве, однако как-то один из старших криптографов по глупости решил проверить справедливость слов шефа. Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств.

Беккер рассеянно кивнул, стараясь осмыслить этот жестокий поворот судьбы. Она отдала это чертово кольцо. - Я пыталась помочь умирающему, - объясняла Росио.  - Но сам он, похоже, этого не. Он… это кольцо… он совал его нам в лицо, тыкал своими изуродованными пальцами. Он все протягивал к нам руку - чтобы мы взяли кольцо. Я не хотела брать, но мой спутник в конце концов его .

Мы служба сопровождения, нас нечего стесняться. Красивые девушки, спутницы для обеда и приемов и все такое прочее. Кто дал вам наш номер. Уверен, наш постоянный клиент. Мы можем обслужить вас по особому тарифу. - Ну… вообще-то никто не давал мне ваш номер специально.

 Шифр-убийца? - переспросил Бринкерхофф. Джабба кивнул: - Да. Нужно ввести ключ, останавливающий червя. Все очень все. Мы признаем, что у нас есть ТРАНСТЕКСТ, а Танкадо вручает нам шифр-убийцу.

Understanding Organic and Inorganic Pigments and Their Areas of Applications

Не упустите. Даже клочка бумаги. - Где теперь это кольцо? - спросил Беккер.

Inorganic pigments are not based on carbon chains and rings. Instead, they consist of dry ground minerals, usually metals and metallic salts. Because of their​.
