Provided herein are processes for preparing glass powder product, the process including steps of: providing a crushing waste glass; sorting the crushed waste glass in a primary air classifier to provide a first stream and a reject stream, the first stream comprising a pulverized glass within a predetermined first particle size range and the reject stream comprising crushed waste glass excluded from the first stream; separating the reject stream based on size to provide a coarse stream and a fine stream, the fine stream having a predetermined second particle size range; and milling the first and fine streams to provide the glass powder product. Glass powder products, as well as systems for producing such glass powder products, are also provided.

A process for making a colored composite pavement structure comprising silylated glass aggregate particles and a polymeric binder composition is disclosed. Systems and methods are also disclosed for providing a colored composite material that cures into a pavement structure. In one embodiment, a colorant concentrate is provided by combining an inorganic colorant with a portion of a first component of a polymeric binder composition. The colorant concentrate can then be combined with the first and second components of the polymeric binder composition to provide a colored polymeric binder composition. The colored polymeric binder composition may then be applied to silylated glass aggregate particles to provide a colored composite material that cures into a pavement structure.

The present invention provides additive manufacturing compositions, also referred as inks in the field of additive manufacturing, which can be fine-tuned with respect to porosity by varying the intensity of the photopolymerisation light source and which can further be used to obtain objects out of glasses, ceramics or glass-ceramics and their respective alloys.

A filler that can suppress thermal expansion of a glass composition with a small amount thereof added and is also excellent in terms of flowability when the glass composition is melted, and a glass composition containing the filler are provided. There is also provided a process for producing a hexagonal phosphate-based compound that can be suitably used as the filler using a simple, industrially advantageous method. The filler of the present invention contains a hexagonal phosphate-based compound that has a purity of 90% or higher and is represented by the following Formula 1, the filler having a content of an ionic compound that is no greater than 1.0 wt %,
K.sub.aZr.sub.b(PO.sub.4).sub.3(1) wherein, in Formula 1, a is a positive number of from 0.8 to 1.2 and b is a positive number satisfying a+4b=9.

An invention is provided for creating smoothed, heat-treated glass fragments. The invention includes placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000 Fahrenheit and rapidly cooled to a temperature below 700 Fahrenheit. The plurality of glass fragments are then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that are suitable for direct handling without hand protection.

Lithium disilicate-apatite glass ceramics comprising transition metal oxide are described which are characterized by a high chemical stability, and the translucence of which can be adjusted as desired, and which can therefore be used in particular as restoration material in dentistry.
