I love my computer, we have been through a lotIt had apple care and that was great but that expired last summerMy power button no longer worksI just don't shut if off because the actual button has no response so I know it won't turn on.The plastic around the screen is also in horrible shape, breaking and chunks missing.The computer itself still works great.Question: How do I go about getting those things fixed, do I just get the apple estimate and go with that?Would it be more cost effective to just get another one, and hope that those problems do not happen with the new aluminum bodies of the pro?
Refractory material is one that retains and maintains its strength at high temperatures without softening or deformation in shapeThe most important chemical composition of refractory is the oxides of aluminum, silicon and magnesiumAnother oxide usually used in refractory is the oxide of calciumFire clays are also widely used in the manufacture of refractoryZirconia is used when the material must withstand extremely high temperaturesSilicon carbide and carbon are two other refractory materials used in some very severe temperature conditions, but they cannot be used in contact with oxygen, as they will oxidize and burn.
It is a material to preserve heat in a fired furnace.
This Site Might Help YouRE: What is Refractory? It has to do something with ceramics or clay.
Refractory is a type of material which is designed for use in high heat environments such as kilns and furnacesThese materials should be chemically and physically stable at higher temperatureThey must be resistant to the thermal shockThey should be chemically inert and have specific values of thermal conductivity and coefficient of thermal expansion.
Throw it away and get a normal computerThe only difference between a Mac and anything else is that they use a different operating system, ignore form factors, and charge you way too much.
