I need to heat up a part of a circuit up to 300°C with ideally a 1.5V alkaline battery and I honestly have very little idea of how this stuff works. I was wondering if a short circuit constructed from a copper wire (60cm in length), tungsten wire (~0.5cm in length) and a 1.5V alkaline battery would work. The length of the wires comes from physical restraints. Will this just burn the battery before it even reaches the desired temperature? Is there possibly a way better solution to solving such a problem (300°C, 1.5V battery)?

The battery doesn’t care about temperature so much as current, and at any particular current you can get hotter by putting the same resistance in a smaller volume. Such as using a shorter length of thinner resistance wire.
Bigger battery cell can supply more current. Find a datasheet for your size of battery.
Batteries do not put out a constant 1.5v, it will be more like 0.8v when the battery is close to dead. You’re not going to get an accurate temperature without some kind of feedback to control the current.
power = current * voltage
current = voltage/resistance
What are you actually trying to accomplish?
