About pressable ceramic investment
Pressable-ceramic investment is one of the product kinds ISO 15912 covers, beside casting investment and brazing investment. On this shelf it is sold as powder, as mixing liquid and with disposable press plungers.
A dental casting investment is a material consisting principally of an allotrope of silica and a bonding agent. The bonding substance may be gypsum, for lower casting temperatures, or phosphates and silica, for higher casting temperatures. In the lost-wax technique a wax pattern is surrounded with a refractory slurry that sets, the pattern is removed by heat, and metal or ceramic is cast into the mold that is left.
ISO 15912 covers casting investment, brazing investment, pressable-ceramic investment and refractory die materials, and classifies them by intended use and by the burn-out procedure the manufacturer recommends.
How the investments and duplicating materials on this shelf differ
- Universal Investment — Phosphate-bonded powder and its mixing liquid, sold for more than one kind of casting.
- Chrome Investment — For partial denture frameworks cast in a higher melting alloy.
- Pressable Ceramic Investment — The mold material for pressed ceramics, not for cast metal.
- Refractory Investment — Material for casts, dies and pegs that must go through the furnace.
- Duplicating Materials & Flasks — Gels, silicones and flasks for copying the master model in investment.
- Duplicating & Die Silicone — A silicone that makes the flexible mould of the master model.
What to look at when choosing an investment
Binder and temperature: gypsum is not chemically stable above 650 °C, so gypsum-bonded investments are typically restricted to castings of conventional gold alloys.
Expansion: high setting expansion has been reported for phosphate-bonded materials, more when they are mixed with a silica sol, the special liquid, than with water. Setting expansion was found to be sensitive to mixing speed and to the liquid to powder ratio.
Strength: investments are brittle and may fracture at clamping points.
Burn-out: ISO 15912 classifies investments by intended use and by the burn-out procedure the manufacturer recommends.
