Can aluminum foil be used in the microwave?
However, the conductive foil is too thin and therefore will lead to a catastrophic reaction. Thin conductive metal process and that its rapid temperature ramping, can lead to fire. Meanwhile, in case of aluminum foil tip generated when the heat-shrinkable cause sparks, which can ignite any flammable materials inside the microwave oven.
Thicker metal can withstand the microwave field and the microwaves reflected off the inner wall of the microwave oven is therefore very thick made of metal; the same token, if the thick metal containers in a microwave oven, the microwave reflective metal container internal the food can not be heated.
Microwave oven microwave frequency radio waves generated belong, usually around 2500MHz. The microwave band has the following characteristics: 1) food and water can be absorbed, the molecule strenuous exercise, heat is generated. 2) can not be absorbed by plastics, ceramics and glass. 3) be under the influence of a conductive metal in a microwave field.
Aluminum foil in the microwave may not use, although supermarkets have special aluminum foil, but still be careful. Because the furnace when heating food in aluminum foil, aluminum foil in contact with the inner wall will give birth to a spark.
