Diamond Enters the GPU Cold Plate: A New Thermal-Management Product
Frore locally integrates a 7 × 7 mm diamond spreader over GPU hotspots in a liquid-cooling plate. Product architecture and test boundaries are public, while temperature and efficiency claims still need independent verification.
MPCVD Equipment & Process
What Should a Company Really Optimize with a Self-Developed MPCVD System?
Self-developed MPCVD equipment is not only about saving on purchase cost. Its deeper value is control, a shorter feedback loop from equipment to material results, and a repeatable manufacturing-learning capability.
Quantum Technology
What Signals Did QWC 2026 Send?
QWC 2026 showed quantum-industry discussion moving from whether technology can work toward whether it can be manufactured, connected and used, with Element Six positioning diamond as a quantum materials platform.
Industry Organization & Business Models
What Can Diamond Learn from Semiconductors?
Diamond does not need to reproduce the entire semiconductor division of labor. It has more to learn from the material-industrialization gates of application definition, standardization, consistency, qualification and design-in.
MPCVD Equipment & Process
How Hard Is It to Measure Temperature Accurately in MPCVD?
Plasma emission, methane-related by-products and substrate emissivity can all push single- and two-color pyrometer readings away from the true substrate temperature in MPCVD.
Diamond Thermal Management
Why Has Diamond Thermal Management Not Reached the Semiconductor Conference Agenda?
Diamond thermal management is already present in advanced-packaging discussions, but diamond has not yet become a standalone semiconductor-conference agenda item.
Diamond Thermal Management
The Hard Part of Diamond Thermal Management May No Longer Be Growing the Diamond
Five barriers—interfaces, reliability, batch consistency, customer qualification and incumbent solutions—separate high-performance diamond from a scalable thermal product.

A system-level thermal-resistance framework for deciding where diamond particles, continuous spreaders and near-junction integration can create real value.
Company Cases
Three Young Founders Want to Make Diamond Wafers. What Did YC Actually Back?
A six-week gap between an unfinished recruiting conversation and Kara Labs' YC launch raises a harder question about how software-style startup methods transfer to advanced materials.
Chinese Company Research
Two Interim Disclosures Show Functional Diamond Is Not Profitable Yet
Huanghe Whirlwind and Power Diamond reported very different interim results, but neither disclosure established functional diamond as a separately verifiable source of profit.
Industry Structure & Business Models
AI Gives Diamond an Opportunity, Not Every Supplier a Strategic Position
AI creates demand for better thermal materials, but a defensible company position comes from solving a specific problem repeatedly and becoming difficult for customers and partners to bypass.
Diamond Thermal Management
The Highest-Performance Diamond Process May Not Build the Largest Market First
MPCVD may retain the high-performance ceiling while HFCVD tests larger-area, lower-cost applications. Industrial scale and maximum material performance need not emerge from the same route.
Industry Structure & Business Models
Diamond Thermal Management Must Sell System Value, Not Thermal Conductivity Alone
CVD diamond suppliers will struggle to escape material-price competition unless they can translate thermal conductivity into lower junction temperature, higher efficiency, stronger reliability, and validated system economics.

Element Six and Orbray: Wafer-Scale Diamond Is About More Than Diameter
The important signal is not two, three, or four inches by itself, but the separation of products by application and the move toward repeatable process and volume-production preparation.
CVD Single-Crystal Diamond
Why Large Single-Crystal Diamond Is Easier to Exhibit Than to Buy
A large diamond sample can prove technical possibility without creating a purchasable seed product. The missing link is a repeatable system for replication, release, finishing, qualification, and supply.
Industry Structure & Business Models
A CVD Diamond Price War Is Ultimately a Cash-Flow Elimination Round
Calls for rational competition cannot remove excess capacity. Survival depends on cash flow, cost position, differentiated products, financing discipline, and conversion of technical claims into paid demand.
