Thin Plates of Ceramic Electrical Insulator

Are you going to make a thick film circuit or onlu for insulation?

2 or 3 milimeter film can be only made by agradation or (spatter?) method, I think

if you dont care of thickness, you can use isingglass (mica )plate. its very thin as same as 0.1mm and can be a good sink. and has a higher insulation intensity.

Does that spattering need to be done under vacuum? If so, how large are the chambers?

of cause it is in the state of vacuum. skill technology now.

the size depends on your requirement.

at least, 2Mx1.6m, no problem.

teh base materials can be glass or film or any other stuff etc.

I can make mgPo4 plates any size and nearly any thickness.

This is a "room temperature" ceramic that is and electrical insulator

Interesting,

What are the mechanical and electrical data?

Gentlemen,

Thank you for the replies. Here are a few more technical details.

1-Many plates will be stacked together to form a large electrical capacitor.

2-Operating voltage will be around 10KV peak at a frequency of 3 KHz.

3-Mechanical properties are not extremely important as the assembly will be supported by a metal structure. Nevertheless, the material should not friable and should hold in one piece during plating and assembly.

Thank you.

I'm intrigued. Can you tell use what you are using it for?

look at his 3 article, he is going to make capacitor of 10kv and 3khz.

this capacitor is widely using in electric industry. as we know this type capacitor almost made of paper with oil immerge (oiled paper). they can be 10, 30, 60kv etc. withstand voltage and 3-5khz at capacitance of 0.01--30uF.

You are right. Using dry material that don't burn like paper, oil, and plastic makes capacitors safer in some demanding applications.

Next, I will have to figure out a way to seal the assembly and install terminals with mineral only material.

Thank you.

Marco

Hi Marcot,

enlarge your momentary thinking to more ordinary capacitors.

(Ceramic may crack and this will destroy your capacitor).

Either metallised Polycarbonate (MKC type capacitors) or metallised PET (MKT type) will do a very good job.

The material is available in almost any thickness. If not sufficiently flexible if thick then make a sandwich of some non-metallised and one metallised sheet.

You can buy the material -thin film vacuum coated - you can do the vacuum coating yourself if you have some M$$ to spend or have to start a business .

(lasermotion.com has some used equipment)

Sealing of the sides should be done carefully with polyester (high-voltage grade).

1 to 10 KV is a dangerous region of voltage and the capacitance you try is certainly lethal if touched with some charge inside.

Safety resistors needed and short circuiting mechanism .

Thank you.

I am well aware of the dangers of high voltage especially with respects to capacitors.

I cannot use polymers as they are flammable.

not all ceramic mtreial is frangible.

once you study more about ceramic, you will know.
