Assessment

Why?

Strongest counted support: The primary study reports the precursor and degassing synthesis route. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly reports high-pressure formation of Na4B60 followed by sodium degassing to synthesize Imma-B60.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

  Primary synthesis description.

• The quoted passage directly reports high-pressure formation of Na4B60 followed by sodium degassing to synthesize Imma-B60.

  The excerpt states the material, precursor, pressure route, and degassing step.

Evidence against

None.

Qualifications

• The synthesis route is condition-dependent: zinc-assisted high-pressure Na4B60 crystal growth precedes vacuum degassing, and temperature/atmosphere determine sodium removal.

  From An open-framework boron allotrope exhibiting high conductivity and plasticity Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Adds precursor crystal-growth aid, degassing conditions, and residual-sodium control scope.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
