Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
A METHOD OF PREPARING A RUTILE-TYPE CRYSTALLINE COMPOUND HAVING THE FORMULA INSBO4 WHICH COMPRISES PREPARING A SOLUTION OF AN INDIUM SALT WHICH IS DECOMPOSABLE TO IN2O3 IN AN OXIDIZING ATMOSPHERE, EVAPORATING THE SALT TO DRYNESS, INTIMATELY ADMIXING THE INDIUM SALT WITH AN SB2O3 COMPACTING THE MIXTURE, AND SLOWLY HEATING THE MIXTURE IN AN OXIDIZING ATMOSPHERE TO DECOMPOSE THE INDIUM SALT TO IN2O3, AND CONTINUING HEATING OF THE MIXTURE TO A TEMPERATURE ABOVE ABOUT 900*C. TO ABOUT 115* C. UNTIL SAID INSBO4 RUTILE-TYPE COMPOUND IS FORMED, THE RATIO OF SAID INDIUM SALT AND SAID SB2O3 BEING SUFFICIENT TO FORM THE COMPOUND INSBO4,

Claim 3
Independent Claim
99 words
A METHOD OF PREPARING A RUTILE-TYPE CRYSTALLINE COMPOUND HAVING THE FORMULA SCSBO4 WHICH COMPRISES PREPARING A SOLUTION OF A SCANDIUM SALT WHICH IS DECOMPOSABLE TO SC2O3 IN AN OXIDIZING ATMOSPHERE, EVAPORATING THE SALT TO DRYNESS, INTIMATELY ADMIXING THE SCANDIUM SALT WITH SB2O3, COMPACTING THE MIXTURE, AND SLOWLY HEATING THE MIXTURE IN AN OXIDIZING ATMOSPHERE TO DECOMPOSE THE SCANDIUM SALT TO SC2O3, AND CONTINUING HEATING OF THE MIXTURE TO A TEMPERATURE ABOVE ABOUT 950*C. TO ABOUT 1200*C. UNTIL SAID SCSBO4 RUTILE-TYPE COMPOUND IS FORMED, THE RATIO OF SAID SCANDIUM SALT AND SAID SB2O3 BEING SUFFICIENT TO FORM THE COMPOUND SCSBO4.
