Silicon Nitride
rods, plates, bearing, pump sleeve, abrasion wheels are produced in
high heat vacuum compression sintering.
-
SILICON NITRIDE
is a formulation of finer particle sizes of silicon powder with carbon
into a homogeneous mixture.
-
-
Fired
at high temperature in the presence of silicon, the vapour silicon
penetrated the compound reacting with the carbonaceous contents, thereby
achieving thorough filing of all porosity in the molecular structure.
-
-
The
characteristics of fine molecular grain structure is smooth and uniform
as a result.
-
-
Properties
-
Maximum
Bulk Density : 3.0 gm/cc
-
Apparent Porosity : 0 (Zero) gm/cc
-
Average
Modulus of Rupture : 50,000 psi +/- (10%)
-
Average
Crushing Strength : approx. 320,000 psi
-
-
With
zero apparent porosity at molecular lever, the bulk density (gm/cc) and
the crushing strength (psi) is many times higher.
-
Silicon Nitride Plates
can be produced in high purity.
-
Its qualities of high Thermal Shock and Mechanical Fracture Toughness makes
it an idea Non-Oxide ceramic for semiconductor Integrated Circuits (IC) Substrates or Base Plates.
-
- Hardness is second to diamond.
