sintered metal-Why Mica Powder Is Use in Many Industries?

Mica is a naturapowder metallly occurring mineral that is based on silicate mineral group。 Potassium， iron， aluminum， magnesium and water in variable amounts compose this mineral。 They may be found in thin sheet like or plate like and the composition may vary with different physical properties。

They are used very often in the paints because of the advantages they offer。 They are the best for external paints and also makepowder metal it anti corrosive。 It gives it a matt finish。 This plays a role of an anti cracking agent and controls the flow of the paint。 It is also known to enhance scrub resistance。 Typical lamellar particle structure of mica powder is good as it is beneficial for resistance against chemicals， heat and ultra violet。

Different grades of mica powders are available and are used for various applications。 They are coarse fine powder， medium fine powder， fine powder and super fine powder。 Metal explosives and disinfectants have coarse fine powder in them and they help in annealing as absorbent。 Medium fine powder is used in welding electrodes， cables and wires。 Their purpose is to act as a protective coat and also improves dielectric properties， electrical and mechanical strength。 Texture paints， acoustical plasters and ceiling tiles use fine powder and improve physical properties， architectural durability， adhesion and water proofing。 The super fine powder is used in paints， plastics， rubber products and paper。 They improve the exterior durability， increase resistance to moisture， flexibility and adhesion。 They improve thermal and dielectric properties， impact strength and also impart resistance to heat。

It is obtained by grinding or breaking mica scrap。 It is a slow， expensive and a complicated process。 This is because the scrap is tough and has a plate like structure。 It is known for its natural brilliance， colour and properties and to preserve these。 For this， care and precaution should be taken to avoidsintered metal any kind of deterioration to these qualities。

Many paint companies have started using mica powder as they are one of the main components because of the benefits。 Many companies have also started manufacturing mica powder。

They have some unique values because of the outstanding chemical， physical， thermal， electrical and mechanical properties。 They are used in electrical apparatus， heating appliances， electrical control， arc lamps， flashers， radio， television， radar， insulators， compass cards， neon lights and many others to add the list。sintered metal It is one of the most vouched things for industries dealing with these。
