Study Notes
Alloys and Their Types
- Alloy: A solid solution formed by mixing metals with other metals or nonmetals; examples include brass and steel.
- Amalgam: An alloy that contains mercury, commonly used in dental fillings.
- Brass: Primarily composed of copper and zinc.
- Bronze: The first alloy created by humans, made from copper and tin.
- Real Gold: A mixture of gold (Au) with copper (Cu) enhances strength and alters color.
- Aluminum: Considered the most abundant alloy.
Ceramics and Related Materials
- Ceramic: A material derived from clay or sand, typically baked at high temperatures, primarily used in pottery.
- Glass: A type of ceramic without a crystalline structure, mainly composed of silicon dioxide (sand).
- Structural Ceramics: These ceramics mainly consist of silicon and aluminum.
- White Wares: A category including porcelain and various ceramic products like dishes and toilets.
Composite Materials
- Composite: Materials formed by embedding one substance within another to combine desirable properties.
- Examples of Composites:
- Cement: Reinforced with iron bars.
- Fiberglass: Made from glass and used in boat hulls.
Plastics and Synthetic Fibers
- Plastics: Synthetic polymers that can be molded into various shapes; nylon and polyethylene are notable examples.
- Synthetic Fiber: A strand of synthetic polymer, used primarily in clothing.
- Differences: Synthetic fibers are created in thread form, while plastics are molded.
Recycling and Environmental Impact
- Recycling: The process of reusing and repurposing materials, preserving natural resources and conserving fossil fuels.
- Encouragement of Recycling: Legally mandated recycling in some states, and deposit laws on cans and bottles promote waste reduction.
Key Processes and Raw Materials
- Polyethylene: Composed of ethene monomers.
- Raw Materials for Plastics: Primarily derived from petroleum products; ores are a source for metals used in alloys.
- Most elements necessary for alloy production are extracted from ores.
Miscellaneous
- Cermets: Composite materials combining the beneficial properties of ceramics and alloys, used in some magnets.
- Fiberglass: A composite made of plastic and glass, utilized in various industries.
