Nanocrystalline kalsilite material was synthesized via a gel‐trapped coprecipitation for dental veneering applications. The prepared kalsilite powder was further mixed with a separately processed low temperature frit (LTF), in different weight ratio to optimize its coefficient of thermal expansion (CTE). These mixes were analyzed for their flexural strength and surface morphology. The cytocompatibility of mixes was investigated with reference to their effect on human buccal epithelial cells (SCC‐25). The flexural strength and CTE values of prepared kalsilite have been found to be comparable to the values obtained for a commercial opaque VMK 95 1M2 (product no. B333250; VITA Zahnfabrik H. Rauter GmbH KG Postfach 1338 D‐79704 Bad Sackingen, Germany). This confirmed the feasibility of prepared kalsilite material for dental veneering application. Kalsilite glass‐ceramic materials caused moderate levels of apoptosis in SCC‐25 cells at higher concentrations and were also tolerable by human RBC as evaluated from hemolytic assay. Human buccal epithelial cells were tolerant to kalsilite glass‐ceramic materials at lower concentrations although higher concentration (500 μg/mL) caused moderate damages in proliferative capacity of SCC‐25. The improved mechanical and biological properties of the prepared kalsilite confirmed its potential use in dental veneering.

Porcelain fused to metal (PFM) has received great attention over the last few years due to its importance in the dentistry. Kalsilite (K 2 O·Al 2 O 3 ·SiO 2 ) is a high thermal expansion porcelain, suitable for bonding to metals. However, kalsilite is a metastable phase which gets converted into crystalline leucite upon heating. In the current work feasibility of developing stable kalsilite phase, dispersion of MgF 2 in it as an additive and using mechanochemical synthesis are studied. Micro fine dental material has been formulated by mixing prepared kalsilite with low temperature frit (LTF) in different ratio. The crystalline phases evolved in fired powders are characterized by powder X-ray diffraction (XRD) technique. Kalsilite with different ratio of LTF has been cold pressed and heat treated to examine its coefficient of thermal expansion (CTE), flexural strength, apparent porosity (AP), bulk density (BD) and microstructure. Results indicate that MgF 2 addition and high milling duration help in kalsilite stabilization. Temperature also plays an important role in this stabilization, and at 1100 ℃ single phase kalsilite formation is observed. Present outcomes demonstrate that it is easily possible to synthesize a stable single phase kalsilite with desirable properties.

This work investigates the decomposition of K‐feldspar into analcime under alkaline hydrothermal conditions. Two types of raw materials, potassic syenite powder and microcline crystal lumps, were used for hydrothermal treatment. Research techniques of minerals alteration path simulation, powder decomposition experiments, and specific observations were conducted. Results show that K‐feldspar did not alter into analcime directly under hydrothermal conditions, and instead, hydroxycancrinite was an important intermediate. Formation route of analcime from potassic syenite powder was derived as follows: syenite dissolution → hydroxycancrinite precipitation → hydroxycancrinite assembling → reversed recrystallization → analcime, where the assembling of hydroxycancrinite into analcime‐shaped spheres was the key step for analcime formation. Above all, a novel and different to natural reaction process with feldspar decomposition and analcime formation process was proposed.
