Zirconia coloring liquids and sintering furnace

[Dental Castle]

hello all.. my first post in here
i just bought my first CAD/CAM system and doing dry zirconia milling.. i was told that using coloring liquids will damage my furnace heating element is that true?
what i should use to dry liquids before i put my zirconia to sintering?
thanks and sorry for my english

Welcome!
All coloring liquids are acidic, even the ones that are claimed to be water base. Use a toaster oven on low heat or a food dehydrator. 15 to 20 minutes at 190 has always been enough for me in the dehydrator.

Run a purge/regeneration cycle regularly.

Dude, overkill. Just grab one from a thrift store for 5 bucks.

Food dehydrator
Works well to rush along models too.

Yep, it's along the same line as my cheaper Wal-Mart one. I'm at about 180 for about 10-15 minutes for my water based liquids.

I like that, multi purpose...without the possibility of toasting your models

Have been using for 6 years now, a coffee cup warming pad for min 30 min. Fits sintering dish perfectly. Never had any issues whatsoever. Seems was made for this instead of keeping your coffee hot

what temperature will it reach to? is it enough or i need higher temperature to dehydrate zircon?

That may be partly why it takes so long (30 mn),that it has to heat up through a sinter dish 1st.?
Maybe using a honeycomb tray would help speed the process along, then load the units in the sinter dish.
Ron @rc75 of TD Dental Supply has great prices for those: https://www.tddentalsupply.com/product/porcelain-accessories/

Side note...Did you know those honeycomb trays come to us from another industry?
Thats whats inside of your cars catalytic converter.

I believe the material itself was initially developed for the space program. If memory serves it is the same as the tiles on the former space shuttle.

I'd suggest it was used on the Shuttle, but not invented for it.
Most of the 'made for Space exploration' stories are exactly that. The pressurized Fisher Space Pen was a commercial item before it was a space use item. Tang, velcro, etc. were the same.

Not that the material didn't exist in some form before.

I used to get a subscription to the print version of this:

Get the latest news and breakthroughs for Design Engineers and manufacturers. Explore Technical Briefs from NASA and top government, commercial laboratories

www.techbriefs.com

I think that is where I originally read about the material.

Im pretty sure we back engineered Tang from the Roswell crash.
