Welcome to Sun Diamond Powder Page. Diamond
is the hardest and the most abrasive-resistant material available
to mankind. These outstanding qualities have extended the use
of diamonds into many industries, and is rapidly expanding into
new fields. We at SMG are proud to provide the best synthetic
and natural diamond powders for industrial, scientific, artistic
and educational communities worldwide.
SUN-PWN (5000X Magnification)
Natural diamond powder (SUN-PWN) was the predominant product
commercially available until 1957, before production of synthetic
diamond powder. It is relatively more expensive than synthetic
diamond powder and for certain polishing applications on materials
like Single Crystal Ferrite, Tungsten Carbide (6% CO), or Ti-6AL-4V
Alloy has a lower cutting rate. However, for polishing of certain
precious stones like sapphire it has higher material removal rate
and it is recommended.
Single crystal synthetic diamond powder (SUN-PWS) was first
invented by GE and it has been commercially available since 1957.
A significant characteristic of synthetically produced mono crystal
diamond powder is it's friability, or material's ability to fracture.
This friability feature, continuously produce fresh cutting surfaces
during polishing. Mono crystal diamond powder is the most vastly
used diamond powder today. It has significantly lower cost and
is well suited for a wide variety of applications in both the
loose and fixed systems. In certain application for polishing
of materials like Single crystal ferrite, Tungsten Carbide (6%
CO), Ti-6AL-4V Alloy, and zirconium oxide have shown significantly
higher material removal rate than natural diamond and produce
a smoother finish.
SUN-PWP (5000X Magnification)
Poly crystaline diamond powder was invented by Du Pont and
has been commercially available since 1970. It is synthesis via
"shock-synthesis". "Shock-synthesis" is basically
the balance of temperature, pressure, time, and a specially formulated
recipe containing graphite the source of convertible carbon.Total
world consumption of this powder is approximately 5 million carats
per year which is much lower than Single crystal synthetic powder
and it has significantly a higher cost. Poly crystaline diamond
powder are used in both loose and fixed abrasive systems. Super
polishing of sapphire, mono crystalline ferrite and titanium carbide
are most commonly achieved by the use of this crystal.
SUN-PWCE (5000X Magnification)
Single crystal synthetic diamond powder is chemically etched.
In order to produce sharper and higher edges, this crystal has
gone through a series of chemical etching. Additional steps of
chemical etching increases the cost of this powder. However, it
has a higher cutting rate than normal single crystal powder and
it produces a finer finish.
