Weight Percent Entry

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.
