Weight Percent Entry
The weight percent entry compositional string must be entered as a string of element and weight percent pairs. For example :
Albite :
ELEM: SiO2 Al2O3 Na2O O
ELWT: 32.132 10.289 8.769 48.810
Enter as : "si32al10na9o48"
YAG :
ELEM: Y2O3 Al2O3 O
ELWT: 44.939 22.721 32.339
Enter as : " y45al23o32"
Lanthanum Hexaboride :
ELEM: La B
ELWT: 68.170 31.830
Enter as : " la68b31"
Note that numbers less than 1 percent must be entered as 1 since the string parser does not support fractional weight percents using a decimal point.
Note that because some formulas are "ambiguous" when parsed one character at a time, use both upper and lower case characters to eliminate confusing the formula parser. For example: "yba2cu3o7" will be interpreted as yttrium, boron and an undefined element "a". Instead, enter the string as "YBa2Cu3O7" and the formula will be parsed correctly.
