    stand (http://maplered.com) ard products
4) Typical applications are:
    a) Grinding wheels
    b) Honing Stone (http://g603.net) s and (http://maplered.com) sticks
    c) Grinding paper and (http://maplered.com) cloth
    d) Lapping and (http://maplered.com) polishing powders
    e) Wiresawing and (http://maplered.com) polishing of Granite (http://tanbrown.org) and (http://maplered.com) Marble (http://www.lightemprador.com)

Wiresawing:
Special micrograins developed in order to give true and (http://maplered.com) smooth cuts with a minimum
on total thickness (TTV),wrap, bow, or surface damage for sawing of:
1) Silicon wafers for electronics
2) Silicon wafers for photovoltaics
3) Gallium arsenide
4) Quardz
5) Glass
6) Ferrite
7) Sapphire
8) Ceramics

Refractories
Chemical inertness at high temperature, high abrasion resistance, low coefficient of thermal expansion, high thermal shock resistance makes silicon carbide an attractive Material (http://g654.org) for several refractory purposes such as:
1) Kiln furniture
2) Aluminum reduction cells
3) Incinerators
4) Bricks for blast furnaces and (http://maplered.com) zinc furnaces
5) Crucibles
6) Monolithics
7) Taphole and (http://maplered.com) runners in melting furnaces

Metallurgical
Metallurgical grade silicon carbide is used in foundries and (http://maplered.com) in the steel industry in the forms of briquettes or loose grains:
1) As alloying elements, replacing the carbon/ferro-silicon combination
2) As a deoxidizing agent
3) As an inoculant

High performance ceramics
Very fine silicon carbide powders, well into the submicron ranges, are used as the key Material (http://g654.org) in high performance ceramics such as:
1) Recrystallized silicon carbide (R-SiC)
2) Reaction bonded silicon carbide (SiSiC) and (http://maplered.com) sintered silicon carbide (SSiC) for typical
3) Applications:
    a) Diffusion components
    b) Kiln furniture
    c) Seal rings
    d) Burner nozzles
    e) Slurry pump housing and (http://maplered.com) impellers
    f) Incinerators


Chemical and (http://maplered.com) physical properties
Silicon carbide is a synthetic Material (http://g654.org) with an outstand (http://maplered.com) ing hardness, only superseded by diamond, B4N and (http://maplered.com) B4C. The chemical inertness to most of the alkaline and (http://maplered.com) acids in combination with its excellent heat and (http://maplered.com) abrasion resistance make silicon carbide very suitable under extreme operation conditions.

Specifications:
1) Vickers hardness: 30 GPA
2) Thermal expansion: 5 x 10-6/0K
3) Thermal conductivity: 41W/m 0K
4) Specific gravity: 3.21g/ccm

Any inquries from you will be highly appreciated.
