Argon gas fill
Argon is a colourless, odourless, non-flammable, non-reactive, inert gas. Argon gas fills are used to reduce heat loss in sealed units by slowing down convection inside the air space. Argon gas is extremely cost-efficient, and works well with Low-e coated glazing. more »

Atomic Layer Deposition in Glass Industry
Atomic Layer Deposition (ALD) is a Chemical Vapor Deposition (CVD) method based on saturating surface reactions. ALD is normally done at pressure of 0.1-10 mbar (hPa, torr) and temperatures of 100-400°C . The method was originally developed in 1970´s [1] to enable manufacturing of Thin Film Electroluminescent (TFEL) Displays, which was the main application for ALD until semiconductor industry found ALD in 90’s for integrated circuit (IC) applications. Currently ALD is finding more and more new application areas in addition to traditional TFEL and IC applications. More recent applications include coatings for photovoltaic applications, optical coatings, barrier coatings on silver etc. ALD is well suitable for both large areas and large batches. Throughput of ALD in batch mode is relatively high, hundreds of square meters per day. A wide variety of materials has been deposited with ALD [2], and typical coating materials in large scale ALD production include oxides (e.g. Al2O3, TiO2, SiO2, ZnO:Al,), nitrides (e.g. TiN) and sulfides (e.g. ZnS). more »

Cerium oxide
Until the 1940's, iron oxide was generally used in glass polishing procedures, although other materials such as silica and tin oxide were also used. In the 1950's, cerium oxide was found to be a superior polishing agent, and is still in use today. more »

Fluoride Removal
The Fluoride removal in drinking water and in wastewater has been subject of many publications and studies, that have better progressively developed the aspects of toxicity on the man and on the environment. The manufacturing firms of fertilizers, of aluminum and glass, traditionally have to tackle this problem and other activities as electronic production, surface treatments of copper and aluminum and stainless steel produce wastewater with a strong presence of Fluoride ion. more »

QPS: A Quality Seal For Insulating Glass Sealants
The question is rather rhetoric, as it is one we already know the answer to: “Why create a quality seal for insulating glass sealants?”
According to the escalating request of quality in the glass industry, the answer is quite simple: quality guarantee.
On the other hand, the process underlying is not as straightforward as it would seem at a first glance. more »

GLASS TECHNOLOGY & FLOW CONTROL ENVIRONMENT
Even If float technology has been developed and explored in details, the requirement of new and more aggressive glasses is incremental to the expected length of float sequences. The extension of the furnace life through dedicated chemistries and long casting sequences is pushing the working environment to more extreme service conditions.
