What is the term for the product of two prime numbers?

Question

Numbers that can be factored down into 2 and only 2 prime numbers, such as:

25 (5 * 5)
9 (3 * 3)
12752041 (3571 * 3571)

Is there a mathematical term for these numbers? I did a bit of Googling, but it's tough to search for what something is called.

Update: To clarify, I meant the square of a single prime number. So n * n where n is prime.

Answer 1

The phrase "prime power" is usually used to refer to numbers of the form $p^n$ with $p$ prime and $n \geq 1$. I imagine "prime squared" or "prime square" is the most reasonable name for what you're describing.
