Introduction
Pigment yellow 14, also known as barium dichromate yellow, is a common yellow pigment. The following is an introduction to the properties, uses, preparation methods and safety information of Yellow 14:
Quality:
- Appearance: Yellow 14 is yellow powder.
- Chemical structure: It is an inorganic pigment with a chemical structure of BaCrO4.
- Durability: Yellow 14 has good durability and is not easily affected by light, heat and chemical effects.
- Spectral properties: Yellow 14 is able to absorb ultraviolet and blue-violet light, reflecting yellow light.
Use:
- Yellow 14 is widely used in coatings, paints, plastics, rubber, ceramics and other industries to provide yellow color effects.
- It is also commonly used in the field of art and painting as a color aid.
Method:
- The preparation of yellow 14 is usually obtained by reacting barium dichromate with the corresponding barium salt. The specific steps involve mixing the two, heating them to high temperatures and holding them for a period of time, then cooling and filtering them to produce a yellow precipitate, and finally drying.
Safety Information:
- Yellow 14 is a relatively safe pigment, but there are still some safety precautions to be aware of:
- Avoid inhaling or coming into contact with yellow 14 powder to avoid irritation of the respiratory tract and skin.
