Materials Table
Material	Position	Hearth / Crucible	Film Number	Density	Z Ratio	Tooling	Comments
Ag	4	C	5	10.5	0.524	140	Brian, could you please check this table? Z ratio should be 0.529
Al	2	C	6	2.7	1.080	118
Al₂O₃	1	C	6	3.97	0.50	169	Z-ratio should be 0.336
Au	4	C	4	19.3	0.381	138	Bazookas can be used at 20-30Å/sec.
AuGe	3	C	5	17.63	0.397	151	Composition unpredictable unless you practically empty the crucible.
Cr	3	H	6	7.2	0.305	140	Do not evaporate more than 200Å of Cr in the E-Beam evaporator.
Fe				7.86	0.349
Ge	3	C	6	5.35	0.516	130
MgO	1		6	3.58	0.411
Mo				10.2	0.257
Ni	1	H	1	8.91	0.331	140	Prone to spitting. Cool down for 15 minutes before venting.
NiCr	1	H	6	8.23	0.321		Density 8.52, z ratio 0.3258
Nb	4	C	6	8.57	0.516 ( should be 0.492)		Cool down for at least 35 minutes before venting.
Pd	1	H	9	12.0	0.357	140
Pt	1	C	8	21.40	0.245	140	Prone to spitting. Evaporate at 1.5Å/sec or less.
Si	2	H	2	2.32	0.712	150	Cool down very slowly after evaporating lest you crack the source.
SiO		C	6	2.13	0.87	132
SiO₂	1	C	6	2.2 ( should be 2.648)	1.07 ( should be 1.000)	140	Please change the crystal and the upper mirror after evaporating oxide.
SrF₂	1	C	6	4.28	0.727	140
Ta	1	H	6	16.6	0.262		Requires extremely high current. Minimum 35 minute cool down. Hearth #3 may be used. Call me before you try Ta.
W	1	C	6	19.3	0.163	138
Ti	3	H	3	4.50	0.628	139
