In 2015 DEKEMA refreshed the series 6 furnace line significantly, now completely prepared for the digital dental lab. And AUSTROMAT 664 and 674 extend DEKEMA high temperature furnaces to ceramic furnace size with huge capacity. All series 6 furnaces offer optional network capabilities, combined with excellent operation.
Silicon nitride (Si 3 N 4) ceramic is a great candidate for clinical applications due to its high fracture toughness, strength, hardness and bio-inertness. This study has focused on the Si 3 N 4 ceramic as a dental core material. The white Si 3 N 4 was prepared by pressureless sintering at relative low sintering temperature of 1650 °C in
Dental ceramics is applied with specific brushes (of various shapes and sizes), in multiple layers. Each layer has to be separately fired in special furnaces at high temperatures (up to 1000 degrees Celsius or 1830 Fahrenheit). During the combustion process, porcelain and metal alloys develop extremely strong chemical bonds between them.
˚˚ As usual for dental ceramics, lithium disilicate materials require a sintering process, which is achieved by a sintering process using a conventional furnace programmed with different firing protocols, according to the material and furnace settings. Nonetheless, all the conventional sintering furnaces share a common
Saffil ® Alumina Fibers are high-purity polycrystalline fibers designed for use in applications up to 1600°C (2912°F). Since their development in the early 1970s, Saffil Fibers have been used successfully to solve problems in demanding high-temperature insulation and many other specialty applications.
Karamanova et al., have elaborated ceramic from blast furnace slag (9.3% of Al 2 O 3), kaolin (33.2% of Al 2 O 3) and sand (0.2% of Al 2 O 3). The obtained ceramics are characterized with a narrow sintering interval at 1200-1220 °C, good degrees of densification and show high crystallinity (pyroxene and anorthite solid solution).
Armil/CFS carries a range of ceramic fiber blankets for applications up to 3000°F (1650°C). Ceramic fiber blankets are lightweight, efficient insulators highly resistant to thermal shock and chemical attack. Durablanket® products are spun from long, high-purity Fiberfrax® ceramic fibers producing a blanket with exceptional handling strength.
2016726• INFILTRATED CERAMICS (INCERAM): - Available as two component system: - Powder: alumina/spinell/zirconia • - Low viscosity glass A slurry of the powder is slip cast on a refractory die and heated in a furnace at 1120 degree centigrade for 10 hrs and then it is infiltrated with the low viscosity glass at 1100 degree centigrade for 4 hrs
ISO 13078-2:2016 determines a degree of firing to be implemented by the user. It represents a test method for adapting the firing program of a dental furnace by determining the degree of firing of fired test specimens for a dental ceramic. The test method is suitable for powdered dental ceramics
The new inFire HTC speed high-temperature furnace speeds up the processing of frameworks and crown copings. The new high-speed sintering programs deliver time savings of up to 85% and even 97% for single tooth restorations. This is the direct result of technologically enhanced heating elements, insulation materials and sintering trays.
low catalytic efficiency and high-emittance ceramic materials were developed in order to increase the capability of a Toughened Uni-Piece Fibrous Insulation (TUFI)-like thermal protection system, with its high-impact resistance, to temperatures above 3000 degree Fahrenheit (F) (1650 degree Celsius.). These ceramics have been
2015623Ceramic materials investigated in this study were displayed in Table 1. A brass master die was machined to approximate dimension of a prepared molar for an all ceramic restoration with 7 mm height, 6 degree of occlusal convergence and a 90 degree shoulder of 1 mm wide finish line (Fig. 1).
20151012The Programat S1 1600 sintering furnace from Ivoclar Vivadent has the ability to reach sintering temperatures up to 1600 degrees and features a new heating element designed for intensive everyday use. It is the newest member of the Programat furnace line.
Our laboratory furnaces feature temperatures up to 1600 degrees Celsius and capacities up to 22 liters. Important specifications to consider when searching for a laboratory furnace include the process temperature, control requirements, dimensions of sample and inner dimensions of chamber or tube, and pressure range.
