I think they use yttria-based silicates mostly for heat insulation. Of course, achieving as light a weight as possible is desirable, as is combating the brittleness associated with ceramics.
They block heat from entering the shuttle.
Most of the space shuttle orbiters are white, covered by ceramic tiles and heat resistent blanketting. Areas which are subject the highest heating on reentry are covered with black tiles.
CThey aren't just any ceramic tiles; they are made of a special synthetic material similiar to ceramic. Their purpose is to prevent the heat from reentering the earth's atmosphere from getting in the shuttle and basically melting the whole thing; kinda like insulation. The Columbia disaster in 2003 was cause by broken tiles.
There are tiles on the entire space shuttle. Every square inch is covered in tiles. The nose, bottom and leading edges of the space shuttle have black tiles while the rest of the space shuttle has white tiles. The nose leading edges and the bottom of the shuttle are the portions of the shuttle that get the most friction/heat from the atmosphere during re-entry.
There is 25,000 tiles on a space shuttle.Thanks

approximately 30 000.

The tiles on the space shuttle form a heat shield. The shuttle enters the Earth's atmosphere at high speed, which creates very high temperatures that would burn up the vehicle if it was not protected.
The black tiles underneath the space shuttle are made of ceramics. Ceramics are already fired and thus able to withstand very high temperatures. The ceramic tiles do oxidize (which means material is lost) and are replaced between missions. The failure on Columbia was due to some of those ceramic tiles having fallen off during take off.

More than 20,000 tiles fit on a space shuttle.

I will make a wild guess and answer the question as if it is about the Space Shuttle. As the Space Shuttle returns to Earth is gets very hot during the reentry to atmosphere part. That means it is travelling further in 1 second than most people travel in their lifetime. moving that fast means making thousands of degrees of temperature on just a small part of the Shuttle. Ceramic tiles will not melt at those temperatures, the rest of the Shuttle certainly will
Idont know, im not a rocket scientest.
Thermosphere is the atmosphere's outermost layer with a very thin air and no definite outer limit. The reason why a space shuttle gets through it is because shuttle orbiters used ceramic tiles and heat protection.
