## What arsenic is used for

Arsenic (As) is better known as a poison, yet high-purity arsenic metal is a building block of **gallium arsenide**, the compound semiconductor behind radio-frequency chips in phones, satellites and radar, as well as many lasers and LEDs. Most arsenic, though, is consumed as arsenic trioxide, historically in **wood preservatives** and still in some **lead alloys** for batteries and ammunition.

### Other uses

- Indium gallium arsenide infrared sensors
- Hardening agent in lead-acid battery grids
- Glass decolourising
- Medicine, where arsenic trioxide treats a form of leukaemia

## Arsenic supply and demand factors

Arsenic is almost entirely a **by-product**, recovered from copper, gold and lead smelting rather than mined for its own sake, so supply depends on what smelters choose to capture. Demand is split between a large, low-value market for arsenic trioxide and a tiny, high-value market for the ultra-pure metal used in gallium arsenide chips. Environmental rules weigh on both: arsenic is toxic, and handling it is costly.

### What moves the price

- Smelter output and recovery decisions in China and Morocco
- Demand for gallium arsenide in phones, satellites and radar
- Restrictions on arsenic-based wood preservatives
- Environmental and safety regulation

## Arsenic price history

Arsenic has been one of the quieter minor metals: supply comes as a smelting by-product, and demand for its main forms is mature. The more interesting price is for high-purity arsenic metal, whose fortunes follow gallium arsenide chip demand and Chinese supply, the dominant source of the metal.

As of October 2026, the Stockatomics benchmark price for arsenic is $1.23 per kg contained.

## Where arsenic is produced

Arsenic is recovered at smelters rather than mined for its own sake. **China** and **Morocco** produce most of the world's arsenic trioxide, and China also supplies most of the high-purity arsenic metal used in electronics. The United States produces no arsenic and relies entirely on imports.

## Why arsenic is a critical mineral

Arsenic is on the **US critical minerals list** and the **EU critical raw materials list**. Its high-purity form is essential to gallium arsenide semiconductors used in defence and communications, supply is a by-product concentrated in China and Morocco, and the United States produces none of it.

## How the arsenic benchmark price is calculated

Stockatomics publishes a monthly US benchmark price for arsenic in US dollars per kg contained, reading as of October 2026. The figure is a price per kg of contained arsenic. It is not a price for gallium arsenide wafers or for arsenic trioxide as such.

### Converting the price

- Per pound: multiply the price per kg by 0.4536
- Per tonne: multiply the price per kg by 1,000

## FAQ

### What is the price of arsenic per kg today?

The Stockatomics US benchmark price of arsenic is $1.23 per kg contained as of October 2026. Stockatomics updates it every month.

### What is arsenic used for in technology?

High-purity arsenic is combined with gallium to make gallium arsenide, a semiconductor used in phone radio chips, satellite solar cells, radar, lasers and LEDs.

### Where does arsenic come from?

It is recovered as a by-product of smelting copper, gold and lead ores, mainly in China and Morocco.

### Does the United States produce arsenic?

No. It imports all of its arsenic, mostly arsenic metal from China and arsenic trioxide from Morocco and elsewhere.

### How is the arsenic benchmark price calculated?

The Stockatomics benchmark for arsenic is a monthly US price in US dollars per kg contained, published every month and current as of October 2026.
