3. CONTENT

 CO PRECIPITATION
 REACTION
 LANGMUIR BLODGETT METHOD
 CONCLUSION
REFERENCES

4. MICROWAVE SYNTHESIS
TO USE MICROWAVE HEATING ,AT LEAST ONE
COMPONENT OF THE REACTION MIXTURE
MUST ABSORB MICROWAVE RADIATION
 THE OSCILLATING ELECTRIC FIELD CHANGES
ITS DIRECTION RAPIDLY SO THAT THE TIME
BETWEEN CHANGES IS MUCH SMALLER ,THEN
THE DIPOLES CANNOT RESPOND FAST
ENOUGH

5. ADVANTAGES
CONVENTIONAL METHOD TAKES ABOUT 24
HOURS TO COMPLETE WHEREAS IT TAKES 2
HOURS USING MICROWAVE SYNTHESIS
 IT HAS LESS PROBLEMS WITH CRACKING,
SINCE HEATING IS FROM INSIDE

6. DISADVANTAGE
 THE REACTION TEMPERATURES ARE HIGH
AND RELATIVELY DIFFICULT TO PRECISELY
CONTROL
