1.Usage of Mica
?
?
Grade | Sieve size (mesh) | Typical uses |
Coarse flakes | 6 | Oil well drilling, artificial snow |
Mid-coarse flakes | 10 | Christmas ornaments, display material |
Fine-coarse flakes | 16 | Concrete block fillers, refractory bricks, gypsum wallboards |
Coarse-fine powder | 30 | Metal annealing, absorbent in explosives, disinfectants, automotive components |
Mid-fine powder | 60 | Welding electrodes, cables, foundry works, pipeline enamels, lubricants, adhesives |
Fine powder | 100 | Texture paints, acoustical plaster, ceiling tiles |
Superfine powder | 325 | Paints, plastics, ruber products, paper, cosmetics |

Chemical Composition | SiO2 | Al2O3 | K2O | Na2O | MgO | Fe2O3 | TiO2 | S+P | CaO | H2O |
Name | Silicon dioxide | Aluminium trioxide | Potassium oxide | Sodium oxide | Magnesium oxide | Iron trioxide | Lilanium dioxide | Sulphur+ calcium | Calcium oxide | Hydrogen oxide |
Content(%) | 44-50 | 20-33 | 9-11 | 0.6-1.8 | 0.32-2 | 2-6 | 0.7-1.2 | 0.02-0.05 | 0.02-0.77 | 2.62 ? |

Proportion | Index of | Brightness | Moisture | Sand | Thickness | Heat | Loss in | PH | Oil | Vickers |
(kg/m3) | refraction | resistance | heating | absorptivity | hardness | |||||
280 | 1.6 | 45°-75° | less | 1% | 60 | More than | 2.8-3% | 7.0-8.0 | 48-500g/100g | 2.5-4 |
than 1% | 1000°C |

Mica's main advantages are insulativity and heat resistance, which are perfect:
?
1). If?mica's thickness reaches 0.015mm, its average breakdown?voltage would be 2.0—5.7kV, puncture strength would be 133- 407KV/mm.
?
2). When mica is heated by temperature of 100-600°C, its elasticity and surface properties will not change.
4. Packing&Loading
Generally,we use 20kg's bag or 500kg's bag to load the mica.
15 tonnes can be loaded into one 20FCL?
?
?
Packing: 25kg/Bags or 50kg/Bags or 1Ton/Bags or as Customer requirement
?
Delivery :7-10 days after your payment confrimed,
