Reference Materials for temperature Calibration.

Dear all,   Be careful with the list on page 148 of the book cited below.  There is an error in the list that can cause you big problems !  The compound K2Cr2O7 has a melting point of 398�C and will evaporate if heated to 665�C !!  The compound they actually refer to is K2CrO4 !   I can tell you, decontaminating a heating stage coated with chromate is not much fun !   Cheers,   Sven Van den Berghe   Dr. Sven Van den Berghe SCK•CEN Microstructure Research Reactor Materials Research Department (RMO) Laboratory for High and Medium Activity (LHMA) Boeretang 200 B-2400 Mol Belgium Tel. : +32 (14) 33 30 64 Fax : +32 (14) 32 12 16 Email : [EMAIL PROTECTED] Internet : http://www.sckcen.be/microstructure                   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, May 07, 2004 1:40 AM To: Subject: Reference Materials for temperature Calibration. Namsoo,   Robert Dinnebier has an extensive list of materials and their transition points (some solid-solid phase transitions, some melting) on his web-site at:-       http://www.mpi-stuttgart.mpg.de/xray/html/temperature_calibration.html   Alternatively, the book "X-ray Diffraction at Elevated Temperatures" Chung, deHaven, Arnold, Ghosh, VCH Publishers, ISBN 0-89573-745-0 has a less extensive list on page 148.   Cheers o----------------------oo0oo---------------------------o      Ian Madsen         Science Adviser - Analytical Science         CSIRO Minerals         Box 312         Clayton South    3169         Victoria         AUSTRALIA      Phone      +61 3 9545 8785  direct                 +61 3 9545 8500  switch                 0417 554 935   mobile      FAX                +61 3 9562 8919      Email  ian.m[EMAIL PROTECTED] o----------------------oo0oo---------------------------o -----Original Message----- From: Namsoo Shin [mailto:[EMAIL PROTECTED] Sent: Friday, 7 May 2004 1:21 AM To: [EMAIL PROTECTED] Subject: Reference Materials for temperature Calibration. Dear all   Can anyone tell me reference powders for XRD temperature calibration in th range from R.T to 1000 degreeC?   Thanking in advance   Namsoo Shin
