What is the name giving to material orbiting the event horizon of a black hole?

Well there is no another name that describes an Event horizon but you can call it "The point of no return" ( acc. to layman's term) i.e. the point at which the gravitational pull becomes so great that even light can't escape from it . It is the boundary in spacetime beyond which events can't effect an outside observer .

What is the name given to material orbiting the event of a black hole?
Event horizon, not event - and it's called the accretion disk.
Can a super heated quasar escape a black hole?
Material in a quasar is ejected away from the black hole, but that material never crosses the event horizon. Nothing that crosses the event horizon can ever escape.
Why wouldn't an accretion disk orbiting a giant star get as hot as an accretion disk orbiting a compact object?
An accretion disk is heated by friction and compression, both of which are greater for material falling into a compact object as the material is forced into a smaller space. The hottest accretion disks would be found around black holes.
Does a white dwarf have a event horizon?
No. Only a black hole has an event horizon.
What is the shape of black hole?
The event horizon of a black hole is spherical.

What is the brilliant light coming from a black hole?
if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.
Can a black hole become full?
No. When matter falls into a black hole it simply increases the black hole's mass, giving it stronger gravity and a larger event horizon.
Make a sentence with the word horizon?
The horizon was beautiful. Black holes have an event horizon.

No. Only a black hole has an event horizon.
What would happen if a neutron star was near to a black hole?
It would all depend on how close the neutron star was. If it was outside the event horizon, then if would be observed to be orbiting "nothing". If it strayed too close to the black hole, then it would be slowly ripped apart, until a slightly larger black hole was all that is left.
What planet has a event horizon?
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
What is the shape of black hole?
The event horizon of a black hole is spherical.
Does a black hole have an horizon?
The so-called "event horizon" of a black hole is the point-of-no-return. That means that anything that gets inside the event horizon can't get out any more, even if if it moves at the speed of light.
What is the length of a black hole?
The diameter is usually considered the diameter of the event horizon. The diameter of this event horizon is directly proportional to the black hole's mass.
