Different processes call for different combinations of chemistry, size distribution and physical properties. The following uses are subject to customer qualification.
Silica is a feedstock for glass. Share the glass type, size limits and any maximums for iron or other impurities. The chemistry target can vary with the colour and type of glass being made.
For glass feed, identify the glass type and any maximum levels for iron and other impurities. Include the preferred feed size and the test methods used to assess incoming material.
Quartz may be evaluated as an ingredient in selected ceramic bodies or glazes. Identify the recipe, firing process and material criteria. Trial pieces can help your team assess appearance and fit with the formulation.
For a ceramic trial, record the body or glaze formulation, firing conditions and the finished properties your team needs to check.
Chips, grit and filler serve different roles in a surface formulation. Specify the target aggregate blend, grain appearance and whiteness. Evaluate the proposed fractions in the intended formulation and finish.
Assess the chip and grit blend together with the filler. Grain appearance, whiteness and the look of the finished surface can all inform the trial.
A foundry enquiry should identify the mould or core system, target grain-size distribution, acceptable fines and binder process. Review the proposed material against the requirements of the casting process.
Specify the mould or core system, binder, target grain-size distribution and acceptable fines when requesting a foundry sample.
Share the lining system or refractory formulation, expected service conditions and preferred gradation. Your technical team can compare the material with the applicable chemistry and performance requirements.
For a refractory or ramming-mass enquiry, share the lining system, expected service conditions and the gradation your formulation requires.
For a mineral filler enquiry, provide target fineness, colour or whiteness, and any relevant dispersion criteria. Evaluate the proposed filler in the actual coating system before specifying a supply grade.
Evaluate filler in the intended coating system. Share the target fineness, whiteness and any dispersion criteria that are part of your acceptance process.
