Mica Powder

Mica Powder is one of our traditionalwpports.Owing to its good properties as high electric insulation and of high resistance to heat ,acid and alkali, mica powder has been widely used in recent years as insulating materials for electric equipment and appliances.Besides it is a new kind of additive suitable fir use in the plastic products,paint,rubber products,welding electrodes and various kind of cosmestics,etc.

It's main physical and chemical properties:

SiO2≥45%

AL2O3≥33%

Fe2O3≤5%

Sand:≤0.5%

Moisture:≤0.5%

Whiteness:68-85

PH 7.5-8.5

Size:In powder,passing through 20,40,60,100,325,1250 mesh,etc.

Packing:In plastic woven bags.

Orders are welcome.

Wollastonite
 
Wollastonite  

Wollastonite is aslo called Calcium Metasilocate with its molecular formular being CaSiO3 .With ideal aspect ratio and fine reinforcement properties,wollastonite of acicular crystal,exported by our Corp,may replace short-fibre asbestos,fibre talcum and glass fibre,etc.This product ,featuring good sealing properties,high melting point,low hot expansion,natural lower iron and very low impurities,is widely used in macromolecular compound materials which will therefore possess the comprehensive proi\perties in increasing strength,hardness,heat-resistance and good electricity,physical&chemical poroperties.At present,owing to its unique physical and chemical properties,wollastonite has been increasingly applied to various industries like metallurgy apoplied to various industrieslike metallurgy,construction,plastic,ceramic,rubber and painting,etc.

Its main physical and chemical properties are shown as follows:

Hardness:4.5 Whiteness:88
Specific Gravity:2.8-2.9 SiO2:45-51%
Melting Point:1500o CaO:44-49%
Loss on Lgnition:<3 Fe2O3:<0.3%

Specofications:

Black Silicon Carbide

 
Black Silicon Carbide  
Black Silicon Carbide is brittle and sharp. It has a good electrical and heat conductivity. Micro hardness is 3100-3280 kg / mm2. Abrasive articles made of it are suited for working on metal and non-metallic material of low-tensive strength such as grey cast iron, brass, aluminium, stone material, leather and rubber etc. Moreover, it can also be used in the manufacture of refractory products and electric industry etc.

Green Silicon Carbide
 
Green Silicon Carbide  
Green Silicon Carbide has high purity. Its quality is brittle. Micro hardness is 3288-3400kg/mm2. Abrasive article made of it are suited for processing non-metallic materials with high hardness and brittle quality such as cemented carbides, optical glass, agate, ceramics as well as hard alloy etc. It can also be used in the manufacture of high-class refractory products, electrothermal products, electrical appliance products and the like.
