Sentences with phrase «silicon oxide»
Silicon oxide refers to a compound made up of silicon and oxygen atoms. It is commonly known as silica or quartz, and it can be found in various forms like sand or glass. Silicon oxide is a key component in many minerals and materials, and it is widely used in industries for its durability and ability to withstand high temperatures. Full definition
