yields of each chemical can then be integrated into mixing formulations to produce a total char yield and the associated weight loss for any anti oxidant solution for examples source materials from equation 1 equation 2 equation 4 and equation 11 are possible sources of phosphorus oxide char material after the heat treatment process source materials from equation 2 and equation 3 are possible sources of aluminum oxide char material source materials from equations 4 through 8 are possible sources of potassium oxide char material source materials from equations 10 through 14 are possible sources of sodium oxide char material source materials from equation 8 through 10 are possible sources of boron oxide char material source materials from equation 15 and equation 16 are possible sources of calcium oxide char material after heat treatments volatiles are released while only stable oxides remain in the final product and react to form a stable mixture of glass ceramic coating material the theoretical calculations of weight loss and char yields for each could be used to calculate the amount of source materials needed to design the particular anti oxidant the weight percent of each oxide material can be achieved by using many possible source materials as shown in table 2 column one in this table contains many possible raw chemicals that can be used in the making of the anti oxidant material and column two contains the possible ranges of each raw material used in this anti oxidant the last eight columns represent the percent of each oxide material after the raw material has been charred at elevated temperatures to remove all volatile materials the volatile materials given.
