Moon Goo and Reaction Materials Explained
Moon Goo and Reaction Materials Explained
Moon Goo is one of the most important raw resource categories in EVE Online’s industrial economy. It forms the foundation of almost all advanced industry, feeding into reactions, Tech II manufacturing, and large-scale alliance production chains.
For industrialists, understanding moon materials is essential because they are not just “mining loot”—they are the starting point of entire high-value production ecosystems.
What Is Moon Goo?
“Moon Goo” is the common term players use for:
Raw materials mined from moons using moon mining structures
These materials are extracted from asteroid-like moon deposits and refined into advanced industrial components through reactions.
In simple terms:
- Ore mining → minerals
- Gas harvesting → gases
- Moon mining → moon goo
Moon Goo is the bridge between mining and advanced manufacturing.
How Moon Mining Works (High-Level Overview)
Moon materials are extracted using:
- Refineries with moon drilling services
- Moon mining drills
- Harvesting cycles that break moon chunks into mineable ore
Once extracted:
- Moon ore is mined
- Transported
- Refined or reacted into usable materials
Categories of Moon Goo
Moon materials are divided into tiers based on rarity and value.
1. Common Moon Materials
These are widely available and form the base of most reaction chains.
Examples:
- Atmospheric Gases
- Evaporite Deposits
- Hydrocarbons
- Silicates
Characteristics:
- High volume
- Low-to-medium value
- Stable supply
2. Uncommon Moon Materials
Mid-tier materials used in more advanced reactions.
Examples:
- Tungsten
- Technetium compounds
- Cobalt
- Chromium-based materials
Characteristics:
- Moderate supply
- Higher value per unit
- Important for composite reactions
3. Rare Moon Materials
High-value industrial components.
Examples:
- Neodymium compounds
- Dysprosium
- Promethium
- Platinum-group materials
Characteristics:
- Limited availability
- High market value
- Critical for Tech II and capital industry chains
4. Exceptional / Strategic Materials
Top-tier moon resources.
Examples:
- High-end isotopes and advanced compounds used in specialized production chains
Characteristics:
- Extremely valuable
- Often regionally concentrated
- Highly contested in nullsec
What Are Reaction Materials?
Reaction materials are the refined products created from Moon Goo through industrial processing.
They are not mined directly. Instead, they are produced via:
Simple and composite reactions in refineries
Why They Matter
Reaction materials are used to build:
- Tech II components
- Ship hulls and subsystems
- Structure components
- Fuel block ingredients
- Advanced industrial goods
From Moon Goo to Reaction Materials (The Chain)
The industrial progression looks like this:
Step 1 – Moon Mining
- Raw moon ore is extracted
↓
Step 2 – Refining / Processing
- Ore is broken down into usable raw materials
↓
Step 3 – Simple Reactions
- Raw moon materials → basic reaction outputs
↓
Step 4 – Composite Reactions
- Multiple reaction materials → advanced compounds
↓
Step 5 – Manufacturing
- Final goods like ships, modules, and structures
Types of Reaction Materials
1. Basic Reaction Outputs
These come from simple reactions.
Examples:
- Carbon Polymers
- Silicon Diborite
- Ceramic Powder
- Hydrocarbon compounds
Use:
- Foundation materials for advanced reactions
2. Advanced Reaction Materials
Created through composite reactions.
Examples:
- Polymeric structures
- Advanced alloys
- Composite fibers
- Structural reinforcement materials
Use:
- Tech II production
- Capital components
- Structure building
3. Specialized Industrial Materials
High-tier outputs used in niche production chains.
Examples:
- Booster-related compounds
- Strategic construction materials
- Rare component precursors
Why Moon Goo Is So Important
Moon Goo drives much of EVE’s economy because:
1. It feeds Tech II production
Almost every Tech II item depends on moon-derived materials.
2. It controls industrial scarcity
Rare moons create economic pressure and market value spikes.
3. It supports alliance economies
Nullsec alliances rely heavily on moon mining income.
4. It stabilises industrial pricing
Moon materials often set baseline costs for advanced industry.
Market Behaviour of Moon Materials
Moon materials behave differently from normal commodities:
High Stability Materials
- Common moon goo
- Large supply, steady demand
- Lower price volatility
High Volatility Materials
- Rare moon materials
- Alliance-controlled supply
- Sudden price spikes due to conflict or shortages
Strategic Materials
- Used in key production chains
- Price strongly influenced by nullsec control
How Industrialists Use Moon Goo
1. Direct Sale (Mining Output)
- Sell raw moon ore or refined materials
- Fast ISK, lower margins
2. Reaction Chains
- Convert moon goo into reaction materials
- Higher ISK efficiency
3. Vertical Integration
- Mine moon materials
- React them
- Manufacture final goods
This is the most profitable industrial approach.
Common Beginner Mistakes
1. Selling raw moon materials too early
You lose value by skipping reactions.
2. Ignoring reaction chains
Moon goo is far more valuable when processed.
3. Not understanding material tiers
Not all moon materials are equal in value or demand.
4. Overproducing low-demand outputs
Some reaction materials have weak markets.
5. Underestimating logistics
Moon goo chains often require multi-step transport systems.
Moon Goo in the Industrial Economy
Moon materials sit at the start of a large chain:
Moon Mining

Refining
↓
Reactions

Advanced Materials
↓
Tech II / Capital Production
↓
Market / Alliance Use
They are one of the core foundations of the entire industrial ecosystem.
Final Summary
Moon Goo refers to the raw materials extracted from moons in EVE Online, forming the base layer of many advanced industrial production chains. These materials are processed through reactions into intermediate and advanced reaction products, which are then used in Tech II manufacturing, capital construction, and structure development.
Understanding moon materials is essential for any serious industrialist because they determine the cost and availability of almost all advanced goods in the game. While raw moon goo can be sold directly, its true value is realised through reaction chains that transform it into high-demand industrial components.
In EVE’s economy, moon goo is not just a resource—it is the foundation of advanced industry itself.
