Introduction of Inorganic Powders
The industrial sector uses finely divided inorganic powders composed of inorganic compounds because they possess distinctive chemical and physical characteristics. The versatile stability of these powders combined with their resistance to high temperatures and chemicals makes them essential in applications such as coatings, pigments, electronic materials, ceramics, building materials and other industries. Because inorganic powders possess particle sizes ranging from micrometers to nanometers they can deliver outstanding dispersibility and surface activity which suits different application requirements.
Material scientists along with engineers and industry professionals require knowledge about inorganic powders. The applications of inorganic powders extend across multiple fields such as coatings and pigments to electronics and biomedicine offering numerous selection options and adaptability. Under harsh conditions including high temperature and chemical corrosion as well as mechanical wear inorganic powders maintain their stability which ensures material reliability and performance over time. Inorganic powders show non-toxic behavior while remaining harmless and fulfilling environmental standards for usage in environmentally sensitive applications. The cost of producing inorganic powders is lower than many alternatives which leads to economic benefits when used for large-scale industrial applications.

Definition of Inorganic Powders
Finely divided solid materials known as inorganic powders contain inorganic compounds including oxides and sulfides along with carbides. Industrial applications benefit from these materials because they maintain consistent chemical makeup with distinct crystalline structures across various sectors. Typically, inorganic powders have particle sizes between micrometers and nanometers. The particle size determines the powder's surface area as well as its dispersibility alongside reactivity which in turn influences how it performs across various applications. Inorganic powders resist chemical reactions and show stability across various chemical environments while avoiding easy corrosion or decomposition. Inorganic powders demonstrate high melting points along with hardness and thermal stability which enables them to perform well under extreme conditions like high temperatures and mechanical wear.
The classification of inorganic powders depends on their chemical composition.
Oxide: The oxide category consists mainly of titanium dioxide, aluminum oxide, and iron oxide which find primary applications in coatings and pigments and serve important functions in the ceramic industry and various other sectors.
Sulfides: Sulfides find common applications in luminescent materials and semiconductor sectors with examples like zinc sulfide and cadmium sulfide.
Carbides: Silicon carbide and tungsten carbide serve as standard examples of carbides. Carbides demonstrate superior hardness and resistance to wear which makes them perfect for manufacturing cutting tools and materials that need to resist wearing out.
Nitrides: Nitrides including silicon nitride and aluminum nitride possess outstanding thermal stability and electrical insulation features which makes them optimal materials for electronic applications and high-temperature structural uses.
Inorganic powders can also be classified by particle size:
Micron sized powder: Micron sized powder consists of particles measured in microns which find applications in conventional industrial areas including building materials and ceramics.
Nanopowder: Nanopowder particles measure in nanometers and this size gives them a larger surface area and increased reactivity which makes them ideal for use in electronics and biomedicine as well as nanotechnology.
