Super diamonds

Materials engineering is the 21st century frontier. Diamonds have incredible properties, and manmade diamonds are even more incredible. It will be very interesting to see what new technologies this material opens up;

old rocks, diamond member........talking about diamonds! trifecta

I'm not wasting 45 minutes on old World War II technologies ... we've been making synthetic diamonds since then ...

And batteries for many, many decades. So new battery technology is not worth talking about. LOL Talk about willful ignorance.

This is WWII technology ... and not difficult ... every diamond mounted on a concrete cutting blade is synthetic ... the downside to these industrial diamonds is they're all contaminated by nitrogen, and are yellow in color ... below "Z" grade ... but still just as hard, just as effective at cutting other things ...

The gullible have to gully I guess ...

are diamonds used in place of quartz in any technology, esp. artificial diamonds?

ChatGPT said:​

Yes, artificial diamonds (synthetic diamonds) are used in high-tech applications, and in some cases, they can replace quartz—but typically only in specialized roles, not common consumer electronics. Here's a breakdown:

---

1. Comparison: Quartz vs Diamond​

Property	Quartz	Diamond
Piezoelectric?	Yes	No (pure diamond is not piezoelectric)
Hardness	7 (Mohs scale)	10 (hardest known material)
Thermal Conductivity	Low	Extremely high
Electrical Insulator?	Yes	Yes (can be doped to conduct)
Used in oscillators?	Yes (standard in watches, etc.)	No (but diamonds used in RF/high-power tech)

---

2. Can Diamonds Replace Quartz in Oscillators?​

• No, not directly. Quartz is piezoelectric, which means it can convert mechanical vibrations into an electrical signal and vice versa — ideal for oscillators, clocks, and sensors.
• Diamond is not piezoelectric in its pure form, so it cannot replace quartz in those typical roles.
• Exception: Some boron-doped diamonds may exhibit limited piezo-like behavior, but this is experimental.

---

3. Where Artificial Diamonds Are Used in Technology​

Here’s where synthetic diamonds are used, often because of their extreme hardness, thermal conductivity, and radiation resistance:

a. Semiconductors (Future Electronics)​

• Diamond-based transistors (FETs): Being developed for high-power, high-frequency, and high-temperature electronics (e.g., military, space, nuclear).
• Advantage: Diamonds can handle higher voltages and heat than silicon or quartz.

b. Heat Spreaders in Electronics​

• Diamonds are excellent thermal conductors and are used as heat sinks or spreaders in laser diodes, CPUs, and power devices.

c. Optics and Lasers​

• Used in high-power laser windows, x-ray lenses, and infrared optics due to transparency and durability.

d. Quantum Computing​

• NV centers (Nitrogen-Vacancy) in diamonds are used as quantum bits (qubits) in quantum computing and sensors.
• NV centers can detect magnetic fields and temperature at nanoscale.

e. Mechanical Tools​

• Drill bits, cutting tools, etc., due to hardness (common for synthetic diamonds).

4. Summary: Diamonds vs Quartz in Technology​

Use Case	Quartz	Artificial Diamond
Oscillators (watches, circuits)	Yes	No
High-power transistors	No	Yes (R&D stage)
Heat management	No	Yes
Quantum sensors/computers	No	Yes (NV centers)
Mechanical cutting tools	No	Yes

---

Final Thought:​

Artificial diamonds don’t replace quartz in common devices like watches or oscillators, but they are being used or explored for next-generation electronics, quantum tech, and heat management — areas where quartz can't compete.

This is WWII technology ... and not difficult ... every diamond mounted on a concrete cutting blade is synthetic ... the downside to these industrial diamonds is they're all contaminated by nitrogen, and are yellow in color ... below "Z" grade ... but still just as hard, just as effective at cutting other things ...

The gullible have to gully I guess ...
