heating silicon

I need to heat silicon from as low as -20C to +15C in batches for processing into an aloy.

Does anyone know how to calculate:

Watts or calories or BTU of heat per degree of temperature increase and time per cubic meter of silicon.

The pure silicon is broken into pieces about the size of potatoes.

I will have to spec a furnace in Kw and recommend a dwell time. Silicon has a good heat conduction. I anticipate using radiant heat over a container of product.

sorry. on to the question.

sorry. on to the question. silicon difluoride- what could be made with these elements? I found it in my old [url=http://theinfraredheaters.com/comfort-zone-or-edenpure.html][color=#000000]infrared heater[/color][/url].

"Boyle's Law," states product of pressure and volume remains a constant, e.g. (4 x 1.0 = 3 x 1.33333) and Pressure * Volume = constant.
Similarly "Charles & Gay Lussacs' law relates to volume V = constant * T (time)
therefore the "Ideal Gas" equation of state constant,"
[b]PV=nRT[/b]
P=Pressure
V= Volume
n = no of moles
R = 8.31 Universal Gas constant Joules/Temp in kelvin[size=9]2[/size9][size=12]0 deg. centigrade = 273.1445(4sf) from memory (check it as many chemistry books differ as it is an unreachable exponent).

TRY A DUAL-WAY VACUUM/COMPRESSION DEVICE... If it is a microchip forget it![/size12][/size]
