Wind tunnel scale and plasma for nano materials

A bulk scale nanomater ia l s pro-

duc t ion facility has been com-

miss ioned by QinetiQ, w h i c h

last year set up its subs idiary

Qinet iQ Nanomater ia l s to

develop bulk n a n o m e t r i c mate-

rials capabili t ies at

Farnborough.

Believed to be the the UK's

first v o l u m e p roduc t i on facility

dedica ted to specialist nano

materials, the facility, formeHy a

r e d u n d a n t w i n d tunnel , com-

pr ises the two p roduc t ion rigs

each capable o f achieving up to

several kilos of mater ia l an

hour, office space and ample

r o o m for p roduc t ion expans i on

and storage.

Much of the p roduc t ion

p roces s and plant has b e e n

deve loped and built u n d e r

exclusive l icence and in consul-

tat ion wi th Oxfordsh i re based

Tetronics Ltd.This p lasma to rch

t echno logy expe r t c o m p a n y

has played a pivotal roll in

def in ing and refining the nano-

met r ic p roduc t i on process ,

essent ia l dur ing the plants com-

miss ioning.

A variety o f ox ides and metal

p o w d e r s can be can p roduced ,

each w i t h ' engineered ' charac-

teristics, w h i c h can have a com-

mercial value b e t w e e n tens and

several t h o u s a n d s o f p o u n d s

pe r kilo.

"Bulk nano p roduc t ion for

m a n y coun t r i e s is cur ren t ly in

the region of 100-200gms/day"

says Dr Paul Reip, MD of

Qine t iQ Nanomater ia ls . "Here

we have the capaci ty to pro-

duce at kg / h r or a coup le of

tons a year."

Dr Reip, expla ins that the com-

pany is cur ren t ly looking at

over 25 nano mater ia l pro jec ts

( none in the c o m p o u n d sec tor

as yet) w i t h the dual aim of

foundry mater ia l sales, bu t

Qinet iQ Nano is a p ionee r of

pera tu re p l a sma (typically in

the t empe ra tu r e range 4,000°C

and 9,000°C) w h i c h acts as a

trolling the p roces s pa ramete rs ,

a range o f materials can be pro-

duced in a variety of particle

sizes. Pure metals , pass iva ted

meta ls (wi th a th in oxide
