Silicon is one of New Zealand’s critical minerals and plays a key role in the technology we rely on every day.
It’s produced from silica (silicon dioxide), which is commonly found in mined sand and quartz.
🔍 Where silicon is used:
🏗️ Glass and ceramics – silica (a silicon compound) is a key ingredient
💻 Semiconductors – the foundation of computer chips and electronics
🔋 Solar panels – the main material in most solar cells
🧪 Sealants and silicones – widely used in construction and everyday products
🔩 Steel production – added to improve strength and quality
⛏️ Starting as mined sand and quartz, silicon plays a behind-the-scenes role in modern life, supporting buildings, electronics, and renewable energy.
