What's the difference between feldspathic and felspathic?
Feldspathic
Definition:
(a.) Alt. of Feldspathose
Example Sentences:
(1) Under four loading conditions, the tensile stress distributions on the ceramics crown were analyzed to evaluate the relations between three kinds of ceramics crown, which were an aluminous porcelain jacket crown, a feldspathic porcelain jacket crown and an Olympus castable ceramics (O.C.C.)
(2) Failure was assumed at a strain level of 0.1%, which corresponds to the tensile failure strain of feldspathic porcelain.
(3) The gel was also applied to glass ceramic, amalgam, hybrid composite, feldspathic porcelain, glass ionomer, gold alloy, silver palladium alloy, and non-precious alloy.
(4) However, the depth of compressive stress that is produced by tempering of feldspathic porcelain has not been determined.
(5) The sintered aluminous porcelains were made from the mixed compacts consisting of 80 wt% germanate-glass and 20 wt% alumina at the densification temperature of 580-820 degrees C. Sintered aluminous porcelains prepared with high refractive germante-glass had a high transparency compared with the other aluminous porcelains, with almost the same transparency as a commercial feldspathic porcelain (body).
(6) This study investigated the effectiveness of tempering and ion-exchange treatments on crack growth and bi-axial flexural strength of seven feldspathic porcelains.
(7) The feldspathic porcelain was lowest in n-value, while the fine-grain ceramic had the highest n-value.
(8) The results of this study suggest that checking in conventional feldspathic porcelains can be promoted by slow cooling rates and an excessive number of firing cycles.
(9) The materials consisted of three low-fusing and one high-fusing feldspathic porcelains and six reinforced dental restorative ceramics which are currently in clinical use.
(10) The crowns, 10 for each group, were made of a feldspathic porcelain (Ceramco), a glass-ceramic material (Dicor), and an alumina-reinforced glass (In-Ceram).
(11) The kinetics of ion exchange strengthening of three feldspathic porcelains were investigated.
(12) Both crown types were veneered with feldspathic porcelain.
(13) Lifetime prediction curves in 37 degrees C water, constructed from the n-values and inert strengths, showed that fatigue failure within five years is a good possibility for feldspathic porcelain specimens at stress levels which can reasonably be anticipated to occur in the oral environment.
(14) The constant stressing rate experiments were carried out at 37 degrees C for all three ceramics in distilled water, and, for the feldspathic porcelain, in artificial saliva as well.
(15) The factors tested were (1) porcelain type (feldspathic [porcelain CE] or high alumina [porcelain VI]), (2) surface treatment (glazed or roughened), (3) priming agent (silane or alcohol), (4) bonding resin (macrofilled or microfilled), and (5) debonding time (30 minutes or 24 hours).
(16) Most commercial dental porcelains designed for ceramo-metallic restorations are partially crystallized feldspathic glasses (glass-ceramics) that consist of low (tetragonal) leucite (K2O.Al2O3.4SiO2) crystals embedded in a glassy matrix.
(17) The purpose of this study was to test the hypothesis that high-leucite content feldspathic porcelain can be strengthened best by thermal tempering followed by ion exchange, compared with either thermal tempering or ion exchange alone.
(18) The dynamic fatigue (constant stressing rate) method was used to obtain subcritical crack growth parameters for three dental ceramics: a feldspathic porcelain, an aluminous porcelain, and a fine-grain, polycrystalline core material.
(19) Ion exchange is a simple, relatively low-temperature process that can have a substantial effect on the flexural strength of feldspathic dental porcelains.
(20) A variety of feldspathic porcelains with low and medium alumina content were tested.
