Graphite mixed with clay is used to create graphite pencils. The clay helps to bind the graphite together, giving the pencil its structure and allowing for smooth and consistent writing or drawing. Different ratios of graphite to clay determine the hardness or softness of the pencil lead.
Graphite mixed with china clay.
Graphite is a soft form of carbon used in pencils. The graphite is mixed with clay, which also contain minerals,
The shiny black substance is graphite. It is mixed with clay to use in pencils.
The formula for pencil lead is a combination of graphite mixed with clay. The most common type contains graphite and clay in a ratio of approximately 80:20. The clay acts as a binder to hold the graphite together and determine the hardness of the lead.
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
Graphite mixed with china clay.
Graphite is used as a lubricant and, mixed with clay, in pencil lead.
Graphite, a form of carbon
The mineral is graphite.
Graphite is the material commonly used in pencils, not metal. The graphite is mixed with clay to create the core of the pencil, which is then encased in wood.
Graphite.
The mineral mixed with clay to make pencil lead is graphite. Graphite is also used as a lubricant for machine parts and as electrodes in batteries due to its ability to conduct electricity.
Graphite is mixed with clay to form refractory crucibles due to it's high melting point, inert nature and abilities to conduct heat.
Graphite is the primary material found in pencils, which is a form of carbon. Graphite is mixed with clay to create the writing material used in pencils.
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
Graphite is a soft form of carbon used in pencils. The graphite is mixed with clay, which also contain minerals,
The lead in pencils is made of the element carbon, in the form of graphite. Graphite powder is mixed with clay and wax. The more graphite the pencil contains, the softer the lead, and darker the mark.
